[요약]
코로나19인해 다가올 4분기 실적은 9천만달러 이상 감소할 것으로 예측하고 있다. 이는 코로나19로 인하여 부품 조달 및 생산이 제한되고 소비자 및 산업 수요 감소로 인해서 제품을 공급할 수 없기 때문에 발생한 것이며, eps 기준 주당 0.5달러 이상 하락할 것으로 현재 예상하고 있다. (가이던스 하향)
하지만 코로나19로 인한 현재 상황에 대응해서 회사의 전략을 수정하거나 장기적인 방향을 변경하지는 않을 것이다. 무엇보다 우리는 시장에서 없어서는 안될 지속가능한 지배적 위치를 확보해왔고, 업계 최고의 수익성과 견고한 재무현황을 유지하고 있다.
현재 코로나19로인한 상황은 단기적으로 성과에 부정적 영향을 미치고 있지만, 장기적으로는 우리에게 큰 기회가 될 것이라고 본다. 우리는 COVID-19가 전 세계의 업무, 엔터테인먼트, 교육, 의료, 사회적 교류 및 상거래에 있어 디지털 및 가상 접근 방식으로 전환을 가속화 할 것이라고 보고 있고, 이러한 변화가 속도를 내면서 세계의 통신 및 클라우드 네트워크에서 더 많은 양의 고성능 광학 장치에 대한 요구가 발생할 것으로 예상하단. 이러한 앞으로의 기회에 있어서 우리는 시장에서 주도적인 위치를 계속 유지해 나갈 것이다.
COVID-19에도 불구하고 통신 전송, 전송 및 데이터 통신 칩에 대한 수요는 3/4 분기에 강력했습니다. 이 제품의 예약은 순차적으로 10 % 이상 증가하여 전분기 대비 1.1에서 1.3으로 증가했습니다. 그러나 이로 인해 기존 공급 문제가 악화되었습니다. 그 결과 통신 및 데이터 통신 매출은 순차적으로 6 % 감소했습니다.
COVID-19에 대한 세계의 경험은 일과 삶의 모든 측면에서 일을하는 방식을 변화시키고 있습니다. 이러한 변화는 통신 및 데이터 통신 제품의 필요성을 직접적으로 이끌어냅니다. 시장은 더 높은 용량으로 확장 할 수 있도록 주요 제품을 중심으로 네트워크를 설계하고 있습니다. 이것은 우리에게 매우 유리합니다. 고속, 저전력 데이터 통신 칩은 5G 및 차세대 데이터 센터 네트워크에서 네트워크 용량과 효율성을 높이는 데 매우 중요합니다.
전년 대비 성장은 3D 센싱을 작년에 비해 더 높은 비율로 제공하는 고객과 3D 센싱 가능 제품에 대한 소비자 수요의 증가에 의해 주도되었습니다. 3 분기에 전세계 카메라 용 레이저 또는 LiDAR의 대량 생산이 급격히 증가했습니다. 우리는 일년 내내 그러한 레이저의 양을 계속 증가시킬 것으로 기대합니다.
우리는 세계를 향한 3D 센싱 또는 LiDAR 지원 카메라의 보급률을 높일 것으로 예상되는 상황을 위해 추가 설계를 포함하여 연말 하반기에 출시 할 다양한 신제품을 보유하고 있습니다. COVID-19로 인해 소비자 물량이나 새로운 프로그램의 타이밍에 영향을 미칠 정도로 자신있게 수량화하기에는 너무 이르지만 상황을 면밀히 모니터링하고 있습니다. 우리는 3D 센싱 시장이 장기적으로 계속 성장할 것이라고 믿습니다.

Alan Lowe -- President and Chief Executive Officer
Thank you Jim. Good morning everyone. At the outset, I want to thank our employees. They have been incredible through this crisis despite each having their own personal challenges, living and working in these times.
They are the ones that have put us in such a great position, both financially as well as with our technology and product leadership. Our employees are absolutely the company's greatest asset, and my top priority is protecting the health and well-being of our employees and their families. I'd also like to thank the rest of our stakeholders including customers, suppliers, and shareholders for their support and partnership. While everyone is surely facing difficult challenges, all have been constructively focused on overcoming these challenges together.
After protecting our employees, my next highest priority is ensuring we do everything we can to help our customers. This is both in the supply of products as well as the execution on new products to ensure future success for our customers and therefore, us. Third-quarter demand was very strong. Our revenue was within the range of our prior guidance but on the lower end due to COVID-19-related challenges that rapidly accelerated late in the third quarter as the virus quickly spread outside of China.
COVID-19 is dramatically impacting our fourth-quarter outlook. We estimate that COVID-19 will impact the fourth-quarter revenue by more than $90 million as the midpoint of our guidance is more than 20% below what we were anticipating for the fourth-quarter before the brunt of our challenges from COVID-19 began. A little more than half of this $90 million is a result of our inability to supply communication products due to both component sourcing and production limitations and the balance from reduced consumer and industrial market demand. We estimate that the COVID-19-related revenue reduction lowers projected fourth-quarter earnings by more than $0.50 per share.
While we continue to react tactically to address the rapidly evolving and fluid situation, COVID-19 does not change our strategic focus or diminish our long-term opportunity. Our strategic focus since we became an independent public company, has been product and technology leadership with close customer partnerships in markets that we expect will have strong growth and will be healthy over the long term. In addition, we have focused keenly on disciplined management over our operations, investments and capital structure. We believe we are seeing the benefits of executing with this focus.
We have attained sustainable technology leadership positions that make us indispensable to the markets we serve. Additionally, we have become financially strong with industry-leading profitability and a very solid balance sheet. We believe COVID-19 will accelerate the shift to increasingly digital and virtual approaches to work, entertainment, education, healthcare, social interaction and commerce around the world. This accelerating shift will stress the world's communications and cloud networks and should, therefore, drive the need for higher volumes of high-performance optical devices.
We believe this will favorably impact our communication business over the long term. We also believe this accelerating shift will favorably impact our laser and 3D sensing lines of business over the long run. As more secure devices and other hardware that are easier to interact with and more autonomous will be needed to consume, produce and communicate digital and virtual content. Because of these trends, we believe our strategy is even more apt than before.
Further, because we believe the markets we address are driven by accelerating long-term growth trends and are critically dependent on the types of products and technology we supply, we are planning to continue to invest strongly in innovation and new customer programs. By doing this, we expect to drive our growth and further our market-leading positions. Our investments will continue to be guided with the strong strategic and financial discipline that has gotten us to this point. I want to be clear that we are also laser-focused on driving increased efficiency and cost savings in all of our operations to further bolster our financial strength.
As we rely on a highly global supply chain, before discussing product line details, I think it is valuable to provide you with some details on the status of our operations around the world. We responded to the COVID-19 outbreak early and rapidly at all of our sites. We quickly implemented company travel restrictions and canceled participation in external events like trade shows and conferences in February. In early March, many of our employees started working from home.
We have not laid off or furloughed employees including those who are not able to perform their work function from home. We are also helping the communities in which we operate. For example, we have used our commercial supply chains to procure and donate personal protective equipment or PPE, to healthcare providers. Our employees have been leveraging internal capabilities to produce and donate limited quantities of PPE, and we have also expanded our charitable donation programs.
In nearly all of our locations around the world, local governments have mandated social distancing measures including shelter-in-place orders. We are deemed an essential business by these local governments due to the key role we play in the global supply chains of critical communications and healthcare systems. As such, we have been encouraged and permitted to continue operations. Regarding our factories in Asia which perform assembly and test operations.
In China, because we had a large number of employees working through the Lunar New Year holiday due to strong demand for our products, we were able to quickly ramp up production from our Shenzhen factory after the extended Lunar New Year holiday. However, our Shenzhen factory was impacted in the third quarter by challenges in obtaining components from third-party suppliers inside and outside of China. While component supply is improving, there continues to be some impact in the fourth quarter. In Thailand, we rapidly implemented employee protective measures in the third quarter.
These measures had not limited output so far but production in Thailand has been impacted by the same challenges that our Shenzhen factory is experiencing with sourcing components. In Malaysia, we use a contract-manufacturing partner for the majority of our telecom transmission revenue. Output was significantly impacted late in the third quarter due to the Malaysian government's movement control order issued on March 16. We had no production for several weeks after this, but have been slowly ramping production since then.
Over the coming weeks, we expect to return to production levels close to those prior to the government order. Our wafer fabs in the U.S., Japan and the U.K. are all operating with some at lower efficiencies than before due to implementing social distancing and other protocols to protect the health of our employees. Our Japan fab is the source of our datacom chips.
Our U.S. fab supplies chips for telecom transport and commercial lasers products. And our U.K. fab supplies chips for telecom transmission products.
The lower efficiency in our Japan and U.K. fabs is limiting our ability to grow to meet strong and increasing customer demand. We are hiring and adding capital equipment to increase our capacity, but this takes time. We use third-party fabs in Taiwan, the U.S.
and the U.K. for 3D sensing and have not seen any impact in our ability to meet customer demand for these products. Outside of these operations, our employees are in general working from home, extensively using virtual meetings and digital collaboration tools. If the increase in network traffic we have created with our virtual meetings, where we have added more than 1 million meeting minutes per week since early February, is an indicator of bandwidth growth then the future is very bright for Lumentum.
We continue to make progress on R&D programs, even with the vast majority of our engineers working from home. We do have a limited number of staff in our labs who are operating the equipment for those working from home. We are continuing the development of new wafer designs for next-generation products in our fabs. All of these essential workers are also following strict social distancing rules and employing other personal protected measures.
Now, I'll turn to the product line details. On our telecom and datacom product lines. Before COVID-19, demand was very strong and accelerating driven by global telecom infrastructure upgrades, the start of 5G deployments and significant cloud data center expansion. We were already supply constrained on most key product lines.
Despite COVID-19, demand was strong throughout the third quarter across telecom transmission, transport and datacom chips. Bookings for these products expanded by more than 10% sequentially, driving book-to-bill to over 1.3, up from 1.1 in the prior quarter. The outbreak however exacerbated existing supply challenges. As a result, telecom and datacom revenue decreased 6% sequentially.
In particular, the supply of telecom transmission products from China and Malaysia was significantly negatively impacted late in the third quarter. Despite these supply challenges, we continue to grow our DCO module revenue and our next-generation indium phosphide high bandwidth components for 600 gig and 800 gig systems. During the quarter, we closed the sale of our Italian lithium niobate wafer fab and continue to ramp down our U.S.-based lithium niobate production. We had approximately $10 million of lithium niobate revenue in the quarter and we expect this to decline to near zero over the next two quarters as we have highlighted previously.
Telecom transport was approximately flat quarter on quarter. These product lines are more reliant on Thailand than China for manufacturing operations, but growth was limited by the supply of key components from third parties in China and elsewhere within Asia. Datacom chip revenue continues to grow strongly increasing more than 20% sequentially as data center and 5G demand was robust. Remaining transceiver revenue was approximately $5 million and will decline to zero in the next quarter or two as planned.
During the third quarter, we introduced key new telecom datacom products. These new products leveraged our highly differentiated indium phosphide and gallium arsenide capabilities and included 50G PAM4 VCSELs and DMLs to enable higher bandwidths, uncooled 100G PAM 4 EMLs to reduce data center power consumption. And a wide set of new pump laser products that increase efficiently and power while lowering cost. These address the full range of optical amplifier applications.
Looking to the fourth quarter, as I indicated earlier, telecom and datacom demand remains robust and strong bookings continue. However, we expect telecom and datacom revenue growth to be limited by COVID-19-related supply constraints. Supply constraints in telecom transmission in Malaysia are improving, but we are not at 100% output yet. We won't be able to satisfy than more than $100 million of current backlog we have for these products until the second half of the calendar year.
Telecom transport revenue is expected to be up sequentially due to progress on relieving supply challenges and new product momentum in the market. Datacom chip revenue is expected to be up sequentially, once again due to continued strong cloud and 5G market demand, but is still gated by capacity in our wafer fab. We are optimistic about the long-term outlook for our telecom and datacom product lines due to expected long-term demand trends, our technology and product leadership position and improving industry dynamics. As I highlighted in my initial remarks, the world's experience with COVID-19 is changing how we do things in all aspects of work and life.
This change directly drives the need for our telecom and datacom products. The market is designing networks around our leading products to enable scaling to higher capacity. This is very favorable to us. Our indium phosphide coherent components and modules enable the higher speed and density needed for higher network bandwidth.
Our high-port count and MxN ROADM technology enables networks to scale capacity much more efficiently. And our higher speed, lower power consumption datacom chips are critically important to drive network capacity and efficiencies in 5G and next-generation data center networks. Turning to industrial and consumer. Our industrial and consumer product lines were down 24% sequentially as expected due to seasonal factors, but up 40% relative to the prior year.
Year-on-year growth was driven by customers incorporating 3D sensing in a higher percentage of their product offerings compared to last year and increased consumer demand for 3D sensing enabled products. We steeply ramped volume production of lasers for world-facing cameras or LiDAR for consumer applications in the third quarter. We expect to continue to ramp volumes of such lasers throughout the calendar year. Looking to our fourth quarter.
Our guidance contemplates 3D sensing declining significantly by more than 40% due to expectations around consumer demand, the potential for smartphone supply chain challenges impacting demand for our products and potential risk around the timing of new customer programs. We have a range of new products we are readying to ramp in the second half of the calendar year including additional world-facing designs that we expect will increase the penetration of world-facing 3D sensing or LiDAR-enabled cameras. It is too early to quantify with confidence any impact to consumer volumes or the timing of new programs due to COVID-19, but we are very closely monitoring the situation. We believe the 3D sensing market will continue to grow over the long term.
Mobile device manufacturers continue to make progress on their plans to incorporate front-facing and world-facing capabilities into a wider range of models. We are engaged with a broad range of customers focused on the consumer, industrial and automotive end markets looking to add 3D sensing or LIDAR capabilities to enable their applications. Now on to lasers. Third-quarter lasers revenue decreased to $43.5 million driven primarily by decline in fiber laser sales.
We expect over the next several quarters that our fiber lasers business will soften further as it is tied to growth in global manufacturing. Our solid-state laser revenue expanded nicely quarter on quarter and attained levels not seen in nearly two years. This was due to strength in certain semiconductor manufacturing end markets including 5G antenna fabrication. We expect these trends to continue into the fourth quarter with fiber laser declines being larger than solid-state growth resulting in laser revenue declining sequentially by approximately 20%.
Throughout my remarks, I've tried to give you much more detail than usual about the status of our market demand for our products, our operations and our ability to supply, given the dynamic challenges the world faces with COVID-19. Before COVID-19, we were challenged to satisfy strong customer demand for many of our communications products. The COVID-19 pandemic has exacerbated the situation. Though our ability to supply these products is getting better, catching up on the strong demand will take a few quarters.
Finally, I tried to highlight that while we are all living through difficult times, our strategy is even more apt and our market position and financial strength even more important. I believe we are well positioned both to weather the short-term and to succeed in the long term. With that, I'll hand it over to Wajid.
Wajid Ali -- Chief Financial Officer
Thank you Alan. Good morning everyone. I too, would like to thank our employees for their dedication and perseverance. I am absolutely amazed at their strong execution in such challenging circumstances.
Before diving into the details, some high-level comments. As Alan highlighted in his opening remarks, COVID-19 is impacting our results and our outlook. We estimate COVID-19 is impacting our fourth-quarter revenue by more than 20% and our earnings by more than 35% or approximately $0.50 per share. Despite these impacts, we have made progress in improving our financial model.
year on year in the third quarter, we achieved 650 and 720 basis points of improvement in non-GAAP gross and operating margins, respectively, and more than a 37% improvement in non-GAAP EPS, despite revenue being down 7%. Our model improvement is also seen in the improving margins in our guidance for the fourth quarter even with a substantially lower top line and a less rich revenue mix relative to the prior year. We continue to make strong investments in new technology and customer programs. This may be obscured in the year-on-year comparisons where R&D spending is down as we have been simultaneously attaining R&D acquisition synergies and cutting investments in underperforming product lines all while ramping investments in areas with stronger outlooks and returns.
On capital structure, as you are aware, in the second quarter, we issued $1.05 billion in convertible debt, paid off our acquisition-related term loan, and repurchased $200 million of our stock. This increased gross cash which is now approximately $1.5 billion, reduced our share count and increased our flexibility to further drive strategic initiatives while reducing the cash cost of our capital. We achieved this capital structure in the second quarter, not anticipating the COVID-19 pandemic. However, as we have often said afterwards, the best time to raise capital is when you don't need it.
The past two months is proof to that adage. We are well positioned financially with a strong margin model, high levels of cash with low interest expense and long maturity financing. Now turning to the third-quarter's numbers. Net revenue for the third quarter was $402.8 million which was down 12% sequentially and 7% year on year.
Our prior guidance assumed COVID-19 would negatively impact revenue by $15 million to $20 million. However, as Alan discussed, we had a larger impact than we assumed due to the spread of the virus beyond China late in the third quarter. We estimate this additional revenue impact was more than $10 million over our guidance assumptions. GAAP gross margin for the second quarter was 39.2%, GAAP operating margin was 10.6% and GAAP diluted net income per share was $0.56.
Third-quarter non-GAAP gross margin was 45.5% which was down 190 basis points sequentially, but up 650 basis points year on year. The sequential decline was driven by lower overall revenues, particularly in industrial and consumer. The year-on-year increase was primarily driven by improvements in telecom and datacom margins as well as acquisition synergies. Non-GAAP operating margin for the third quarter was 25% which was down 380 basis points sequentially, but up by 720 basis points year on year.
Sequential and year-on-year changes were driven by the same factors as the gross margin improvement. Non-GAAP operating expenses totaled $82.7 million or 20.5% of revenue. SG&A expense was $38.4 million. R&D expense was $44.3 million.
The sequential decline in operating expenses was driven by the combination of reduced trade show and travel expenses and the realization of additional acquisition synergies which were partially offset by higher fringe rates associated with the new calendar year. Third-quarter non-GAAP net income was $98 million. This includes $3.6 million of net interest and other income and $6.3 million of tax expense. Non-GAAP diluted net income per share was $1.26 based on a fully diluted share count of 77.5 million.
Now turning to segment details. Third-quarter optical communications segment revenue at $359.3 million decreased 12% sequentially due primarily to 3D sensing seasonality and COVID-19 related supply limitations. Year-on-year optical communications segment revenue reduced 5% due to lower telecom and datacom revenue with the exit of datacom modules and COVID-19 supply limitations which more than offset higher 3D sensing revenue. optical communications segment gross margin at 45% decreased 300 basis points sequentially due to the revenue reduction and a less favorable product mix but increased 700 basis points year on year due to a more favorable mix of products, improved telecom and datacom margins and acquisition synergies.
Our laser segment revenue at $43.5 million decreased 10% sequentially and 21% year on year primarily due to lower fiber laser sales. Third-quarter lasers gross margin increased to 49.7% due to a better product mix and lower manufacturing costs. On the balance sheet. We ended the third quarter with $1.45 billion in cash and short-term investments, up from approximately $1.3 billion in the prior quarter.
We have $1.5 billion in aggregate principal convertible notes and no term debt. Of these convertible notes, $450 million is due in 2024 and $1.05 billion is due in 2026. The total cash interest expense associated with these notes is approximately $6 million per year. And now an update on synergies.
Through the third quarter of fiscal '20, we completed actions that will result in approximately $100 million of annual expense synergies. As a reminder, we are targeting a total of $110 million in annual run rate acquisition synergies with the remaining $10 million to be attained over the next few quarters. Turning now to our guidance for the fourth quarter. The projections we are providing today are also on a non-GAAP basis and are based on our assumptions as of today.
Please note, the guidance we are providing today incorporates our current expectations for supply and demand reductions related to COVID-19. We are providing a wider than normal revenue range to incorporate uncertainty around the impact of COVID-19. We project net revenue for the fourth quarter will be in the range of $325 million to $365 million. At the midpoint, this revenue projection includes telecom and datacom approximately flat with growth limited by continuing COVID-19 supply limitations.
This includes declines from discontinued products which are estimated to be $6 million to $8 million. Industrial and consumer decreasing by more than 40% due to expectations around consumer spending trends in a macro slowdown and the timing of new programs. And commercial lasers decreasing by approximately 20% due to end market demand, caused by the slowdown in industrial production globally. Based on this, we project fourth quarter operating margin to be in the range of 18% to 21%, and diluted net income per share to be in the range of $0.70 to $0.90.
These projections incorporate an approximate share count of 78 million and an estimated other income of $1 million which is lower than the $3.5 million in the prior quarter due to lower interest rates in general and are taking more conservative positions in our short-term investments. With that, I'll turn the call back to Jim to start the Q&A session. Jim?
Jim Fanucchi -- Investor Relations Contact
Thank you Wajid. Before turning the call over to the operator to start the question-and-answer session, I would like to ask everyone to keep to one question and one follow-up. This should help us get to everyone before the end of our allotted time. Operator, let's begin the question-and-answer session.
Questions & Answers:
Operator
[Operator instructions] The first question is from Samik Chatterjee with JP Morgan. Your line is open.
Samik Chatterjee -- J.P. Morgan -- Analyst
Hi good morning. Thanks for taking my question. I appreciate all your comments about the supply chain constraints you're seeing. Just wanted to get more visibility about the aspects of your business where you're seeing demand reductions which you mentioned a couple of times? And how are you thinking about maybe the recovery of the $90 million of headwinds that you're calling out through the remaining quarters? And I have a follow-up.
Alan Lowe -- President and Chief Executive Officer
Sure. Thanks, Samik. Well, so the dynamics of the supply chain are really around ability to get components sourced from both within China as well as, for instance, the Philippines and Malaysia. We believe that that situation is getting much better, but the first half of this quarter was impacted pretty dramatically.
And then secondly, our ability to ramp up our contract manufacturing in Malaysia, and that's happening as well. But the first half of the quarter was dramatically below 100% production. And we believe that in the next couple of weeks, that will be back to close to 100%. I think from our perspective, the demand for datacom chips, telecom, transport and transmission is accelerating.
And we believe that as we get back to 100% capacity, and we bring on more capital which we have placed on order to be able to catch up with this demand. But I think it's going to be sustainable, will allow us to grow both datacom, telecom transport and transmission in the first fiscal and second fiscal quarters.
Samik Chatterjee -- J.P. Morgan -- Analyst
OK. Got it. And as a follow up, we've seen some of your peers report acceleration in the deployment piece for 5G infrastructure in China. Can you give us a sense if revenues, I think Huawei revenues, you said last quarter was $60 million, if that -- what was the number this quarter that you just reported? And what's embedded in your guide? Are you seeing kind of a similar acceleration as your peers are reporting?
Wajid Ali -- Chief Financial Officer
Yes. So we are seeing -- certainly, we have very strong datacom chip demand. That is driven in part by 5G deployments. And this quarter had an incredibly strong bookings presumably driven by a lot of 5G.
Can you remind me the second part of your question?
Samik Chatterjee -- J.P. Morgan -- Analyst
What -- I think last quarter, you said Huawei revenues were $60 million. So I was just asking if that's in -- what did you see in terms of trends in the reported quarter? And what's embedded in your guide?
Wajid Ali -- Chief Financial Officer
That revenue has declined a bit. We don't provide revenue by customer on a quarterly basis. But you can imagine that is down in the -- down 20% sequentially.
Samik Chatterjee -- J.P. Morgan -- Analyst
OK. Thank you.
Operator
The next question is from Rod Hall with Goldman Sachs. Your line is open.
Rod Hall -- Goldman Sachs -- Analyst
Yeah. Thanks guys. Thanks for taking my question. I just thought I'd go back to the $90 million impact on the guidance and sort of walk through the add up on that.
So I would estimate, and I'd like to get clarification on whether this is right or not, but that the 3D sensing impact was about $40 million of that. And then if lasers is down 20%, that's just over four. So then is it all -- like the rest of it is telecom and datacom revenue you think you would have had, but you don't or could you just walk back through that and clarify how that breaks down by the different business units. And then I have a follow-up.
Alan Lowe -- President and Chief Executive Officer
Yeah. I think -- yes, thanks, Rod. I think in general, from a demand standpoint, you're pretty close. I think 3D sensing we said was going to be down 40% or more.
I think the balance of approximately $45 million to $50 million is our ability to supply. In that majority of that comes from our inability to ramp our production in Malaysia in the first half of the fiscal -- yes, first half of the quarter, as well as to secure components. And so we have orders, we have demand. Our customers are having daily phone calls with us as to how we prioritize them, how we get them their product.
I'd say north of $50 million is our inability to supply. And we believe that had we not had the pandemic, our capacity would be aligned with that demand, and we would have been able to produce it. So that's where the math comes from.
Rod Hall -- Goldman Sachs -- Analyst
OK. Yes, that makes sense. I wanted to go back to this comment on -- that you made in the slide on the potential delay in customer programs. And I know you say it's too early to know.
When do you think you will know on 3D sensing, whether programs are delayed? And can you give us any idea on how we should think about seasonality now or you just don't know yourselves? I mean, is seasonality likely to shift more into Q4 at this stage, you think or just too hard to tell, but mainly I'm interested in when you'll find out.
Alan Lowe -- President and Chief Executive Officer
Yes, Rod, it is really hard to tell. And I think we find out when they tell us. And so I think from that perspective, we are ready. We have the product, a whole new set of chips ready to go and waiting for not just one customer, but multiple customers to tell us when they're ready to ramp those products.
And there's a very clear date that they tell us and it's a loud scream that we can hear around the world when they say go. So it's -- there's no time line as to when they do that. It's really more of a make sure we're ready to go. And when they say go, we have to jump high.
Rod Hall -- Goldman Sachs -- Analyst
Yes. And then just clarifying the Huawei point, you said down 20% quarter on quarter or down 20% off that $60 million level. I guess that's for March, right? And then I don't know if you said in the guide what Huawei impact is, but it would be nice to get that as well. And then that's it for me.
Wajid Ali -- Chief Financial Officer
Yeah. So I would anticipate at roughly the same level.
Rod Hall -- Goldman Sachs -- Analyst
So minus 20% on the $60 million?
Wajid Ali -- Chief Financial Officer
Correct.
Alan Lowe -- President and Chief Executive Officer
Just to be clear, that's a supply constraint number, given the constraints we're having on ability to provide telecom transport for that matter as well as transmission. So certainly, the demand is higher than that.
Rod Hall -- Goldman Sachs -- Analyst
Right. OK. Appreciate it. Thanks guys.
Alan Lowe -- President and Chief Executive Officer
Thanks Rod.

The next question is from Alex Henderson with Needham. Your line is open.
Alex Henderson -- Needham and Company -- Analyst
Great. Thank you very much. So I was hoping you could talk a little bit about the competitive circumstances around the 3D environment. Obviously, it's difficult to time when production will ramp up for that.
But have you seen any change in dynamics? I think when we talked back in March, you talked about picking up some share because of a competitor's inability to supply. Is that still the case or have you seen any change in that dynamic at this point? And do you anticipate the products in the back half to be the more advanced products on a broader set of platforms, therefore, continued high share in the back half?
Alan Lowe -- President and Chief Executive Officer
Yeah. Thanks Alex. I'd say that it's hard to say exactly what's going on with our competitor. I think our focus is making sure we have the mind share with our customer as they roll out new products.
And so I'd say that the product we talked about in the script, the world-facing LiDAR application. We have an extremely high share of that. We expect to continue to keep that as well as any new chips as they use us as more their development arm and priority moving forward. And I think you're right, I think the technology advancements on these new chips makes it not as easy to catch up as fast.
And so after three years, I think that our competitors are getting it, but now we're moving to the next one.
Alex Henderson -- Needham and Company -- Analyst
And then just one more question on the operating lines. Clearly, there are some cost benefits to not doing as much travel and the like. And some of that is probably going to be impacting the June quarter. Given what you're saying about your operating margins, can you talk about what's going on with the opex on a more sustainable basis? Are you also trimming back some costs there? Any guidance on whether there's additional synergies on the R&D would be helpful particularly.
Thanks.
Wajid Ali -- Chief Financial Officer
Yeah. Hi Alex. Well, I'll take that. It's Wajid.
So on the travel, the way to think about kind of travel reductions quarter-to-quarter. Moving from fiscal Q3 to Q4, we should probably think about it in the $2 million to $3 million range moving from one quarter to the next. Our expectation is that there will be some travel that starts up again as June rolls around. There certainly is an itch from our sales team as well as our operations team to get back into normal, especially with the number of capital deployments that Alan talked about in his script that we've got going on specifically at our U.K.
facility as well as Caswell. So we do need to have our teams start moving around like that. But I think you should think about it from a $2 million to $3 million a quarter standpoint. As far as kind of reducing R&D at an overall level just because of what we're looking at as a COVID-19 issue, that's not occurring.
We're continuing to invest. You can take a look at our careers website on lumentum.com. We're actively hiring across multiple functions, specifically in R&D. Our direct labor hires in the U.K.
over the next year will probably increase a couple of hundred folks just to ramp up with our transmission products. And so right now, we're just trying to figure out how do we get everybody trained and everybody going. So we're certainly in the mode of leaning in as far as additional targeted hires to support our R&D programs. And I would like to mention, they are targeted hires, so it's not across the board, but we're certainly leaning in from that standpoint because our objective is to stay ahead of the competition as we've done in most of our markets, if not all.
And so that's the mindset of the management team. But yes, you'll see some benefits in opex just because of travel delays and things of that nature.

The next question is from Tom O'Malley with Barclays. Your line is open.
Tom O'Malley -- Barclays -- Analyst
Hey guys. Thanks for taking my question. I just wanted to talk a little longer-term on the operating model as well. Clearly, you guys have described some manufacturing that you think is picking back up in the next couple of weeks in Malaysia.
Can you talk about the midpoint of your guidance, when are you assuming that Malaysia is back to 100%? And then within your own factories, how long does the operating margin pressure kind of exists? Is this something that likely lingers into the following quarters or are you able to get these things corrected in the next couple of weeks?
Alan Lowe -- President and Chief Executive Officer
Well, I think we've gotten the go-ahead to bring back all the employees in Malaysia. So that's happening now. We expect that that will take another week and then we have the cycle time of the product coming through. So I'd say within the next two to three weeks, we should be close to 100%.
But keep in mind that there are social distancing limitations that won't get us all the way back with the current headcount. So we're hiring, we're adding capital. But I think that by the end of May, we should be back close to where we were in February. I'd say that the other areas of focus are, as Wajid talked about, our U.K.
fab and our Japan fab, there is just so much demand that we need to be able to get more wafers out and improve the yields and drive the cost and things like that. And that's really what we're focused on. So I would say that I don't have a crystal ball as to when this whole pandemic will end. But I'd say that we probably, as we enter into July and August, we should be back to near-normal from what I can tell.
Tom O'Malley -- Barclays -- Analyst
Great. Thanks. And then the second one is just about largest customers. Your team just came out.
It looks like there's two customers that represented about 37% of revenue. Could you tell us how big your largest customer was? And it looks as though it's down pretty heavily into June. I am just looking at the supply chain, it's down as well. But can you talk about just the share there.
You obviously talked about a world-facing sensor, but your existing sensors, particularly in the front facing, is share maintaining or is that just a broader unit depression?
Chris Coldren -- Senior Vice President of Strategy and Corporate Development
Yes. So our -- Go ahead, Alan.
Alan Lowe -- President and Chief Executive Officer
No. Go ahead. Go ahead, Chris.
Chris Coldren -- Senior Vice President of Strategy and Corporate Development
I was going to say, our largest customer is running north of $90 million a quarter. I don't want to get any more precise than that, and I'll hand it to Alan to talk about share.
Alan Lowe -- President and Chief Executive Officer
No. I think we're comfortable with our share on that customer. And I think that, as I've said before, our focus is on making sure that we enable the next-generation of products. And that we go back to the kind of share we had three years ago and over the last couple of years.
So that's kind of our focus, and we expect it to do quite well as the next-generation of products come out.

The next question is from Meta Marshall with Morgan Stanley. Your line is open.
Meta Marshall -- Morgan Stanley -- Analyst
Great. Thanks. I just wanted to dive into kind of the China base revenue. Just with the tenders being granted or a number of the tenders kind of being granted over the past couple of weeks.
Can you just give a sense of how that should flow through to your revenue or demand or pipeline or how many of your kind of past orders do you estimate have been kind of getting ready for some of those tenders. And then maybe just on the datacom chip side, should we consider that that's all kind of coming from one customer or is there a growing set of customers for those chipsets? Thanks.
Alan Lowe -- President and Chief Executive Officer
Well, I'll answer the second one first because that's easy. That if you look at the datacom customer base a year and a half ago when the acquisition completed, it was very concentrated on one lead customer. I'd say that now it's extremely diverse. We're seeing, as we exited the module business, customers came to us because we were no longer a threat to compete with them.
And so we've seen a broadening of our customer base, and we've seen a growing set of customers coming to us especially on -- well, existing products, but with our technology development on the products I talked about in the script. And also on our VCSELs, we've seen really a rapid acceleration of customer base growth there. As far as China, there is a lot of activity today. I am on calls and escalations with many of our Chinese customers to be able to supply what they need, and that ranges from datacom chips to high-end ROADMs, high-port count ROADMs, MxN ROADMs as well as transmission products.
And so I'd say that the demand is real. Product is being deployed. It's not being stockpiled from what we can tell because I think that the second half of the calendar year, there's going to be a major deployment in China. So getting ready for that.
Meta Marshall -- Morgan Stanley -- Analyst
Got it. Thanks.
Operator
The next question is from John Marchetti with Stifel. Your line is open.
John Marchetti -- Stifel Financial Corp. -- Analyst
Thanks very much. I just wanted to follow-up on your last comment there, where you're talking about some major deployments scheduled for the second half of the year. With some of the renewed noise around additional China sanctions and some things like that way. Do you envision if something were to come down that you'd have to halt like you did in May of last year or do you think that with what you learned there that you'd be able to continue to supply into China if tensions between the U.S.
and some of those OEMs continues to escalate?
Alan Lowe -- President and Chief Executive Officer
Well, I mean I think it's hard to speculate on what ruling or if a ruling comes down, we will certainly abide by any laws and restrictions but it really comes down to what is that. I think as we look today, the de minimis rule limits very little of what we could have shipped. And so from that perspective, depending on what changes happen, if that limit changes to a lower number, I think we're probably OK. If it changes to zero, then that's a different matter.
So it's hard to speculate, but of course, we're going to abide by the laws and make sure that we figure out how to support our customers, but at the same time, also do the right thing.
John Marchetti -- Stifel Financial Corp. -- Analyst
And then maybe just as a follow-up to some of this. If you had been able to secure supply and ship as normal, do you think that the book-to-bill in the telecom and datacom segment would still have been above one? Just trying to get a sense of what that underlying sort of demand trend looks like if you have been able to meet that demand in the quarter?
Alan Lowe -- President and Chief Executive Officer
Well, clearly, if we've been able to ship more, the book-to-bill would have been lower because the billings would have been higher. So I don't think there's a lot of artificial bookings or double bookings, but we'll see when we add capacity. I think we've got a long-haul to get back to more equilibrium between our ability to supply what the customers need and what they're deploying in the field. So I think in our telecom datacom business, there are fundamental underlying reasons for growth in that business.
And I said in the script, we're creating video minutes on how we do business. And I think that is part of the new normal. So bandwidth requirements are continuing to grow, and I don't see an end in sight for that.

The next question is from George Notter with Jefferies. Your line is open.
George Notter -- Jefferies -- Analyst
Hi guys. Thanks very much. I guess I wanted to ask about any views you guys might have on the long-term structure of the market competitively as we think about this COVID-19 experience and you think about maybe some of the smaller competitors in the space, do you see this whole experience driving consolidation? Does it impact their ability to drive innovation, like market share changes? Like how do you think the bigger picture changes longer-term on share?
Alan Lowe -- President and Chief Executive Officer
Yeah. I mean, it's hard to speculate how it sorts its way out. I think, as Wajid highlighted, having a strong financial business model with a very strong balance sheet allows us to lean in and invest, and that's what we're doing. We are hiring R&D.
We're investing. We intend to come out of this even -- with even better product differentiation than we went in. So I think it's going to be very hard for the small guys to keep up, but we'll see. I think there'll be opportunities.
But I'd say that also over the last three years, there's been a lot of consolidation. And so the market landscape is in a pretty healthy position today. So we'll see what happens. But our focus is satisfying our customers, investing in new products and technology and differentiation.
So that when we come out of the other end, we are even better positioned.
George Notter -- Jefferies -- Analyst

The next question is from Simon Leopold with Raymond James. Your line is open.
Simon Leopold -- Raymond James -- Analyst
Great. Thanks for taking the question. A couple of things I wanted to ask. One was, Alan, when you talked about the $90 million, you talked about over $50 million being supply chain related.
So that implies less than $40 million being demand related. Could you maybe unpack that a bit between 3D and industrial or commercial lasers -- the commercial lasers and help us understand what you think about for the prospect for recovery, particularly given that some of the end markets like auto manufacturing seem like they're struggling to turn up factories, etc. Just your outlook on the demand aspect of the COVID-19 guidance?
Alan Lowe -- President and Chief Executive Officer
Sure, sure. I think just to note, we said more than $90 million. So we expect that between the supply and demand, we probably could have done more than $90 million in Q4. So yes, you're right.
It's probably north of $50 million of supply and our ability to ramp up, mainly the Malaysian operations. So that's really impacting our Q4 but the prospects for recovery, I'd say you're right. I mean on the lasers business, we think it's several quarters until the global manufacturing infrastructure comes back to normal. So I think we're at a new lower level for lasers, probably through the calendar year.
Again, I don't have a crystal ball. And then 3D sensing, it's really hard to tell. I mean, our focus is making sure we're there for our customer when they need us, especially on the new products. But it's hard to know with the levels of unemployment, are people going to go out and buy high-end phones or when they'll do that.
I think fundamentally, people will come back and continue to buy, consumers tend to be resilient. So it's really more difficult to project that one. But I'd say on telecom datacom, I'm not losing a lot of sleep on worrying about whether or not there's demand there.
Simon Leopold -- Raymond James -- Analyst
OK. And just as a follow-up, I wanted to get your thoughts on Lumentum's prospects and what you think your role would be in the emerging market for ZR modules?
Chris Coldren -- Senior Vice President of Strategy and Corporate Development
Simon, this is Chris. Yeah, so certainly, we -- one of our motivations when we acquired Oclaro was to get the industry-leading indium phosphide component and module capabilities, and we continue to invest strongly in that capability and are developing those products as well as a whole wide range of DCO modules that, whether they be 100 gig, 200 gig, 400-gig and eventually above and underlying supporting components for those customers who either build modules or linecards themselves. We expect that the market for 400-gig and at the module level, we'll start ramping up probably later this calendar year, so that could be much more meaningful in the following years, but it's an exciting market for us, and we think we're very well positioned with our indium phosphide technology.

The next question is from Tim Savageaux with Northland Capital Management. Your line is open.
Tim Savageaux -- Northland Capital Management -- Analyst
Hey good morning. A question over on the telecom datacom side. I think you'd referenced a continuation of strong booking trend into the June quarter, fiscal Q4. I wonder if we can get any more color on that, whether you've seen an acceleration and expect, given the supply constraints of book-to-bill and kind of similar or backlog build of similar levels.
And as you see those orders materialize, are you able to discern drivers, namely capacity additions driven by network traffic growth kind of in the U.S. and EMEA versus what appears to be pretty strong 5G-driven growth in China?
Alan Lowe -- President and Chief Executive Officer
Yeah. So we saw a continuation of the strong bookings in telecom datacom. It didn't change our ability to supply, that's for sure. But I do think the fundamental drivers are North America bandwidth, hyperscale kinds of deployments as well as connecting all of the people working from home and the use of virtual collaboration tools and things like that.
I'd say that 5G in China is back and rolling. And so building out both the fronthaul and backhaul part of that network as well as the regional metro networks with ROADMs and transmission products is happening. So I think from that perspective, I don't see a slowdown. And I see more of a pent-up lack of deployments over the last -- the first calendar quarter in China that's now starting to ramp-up in a meaningful way.
Tim Savageaux -- Northland Capital Management -- Analyst
And just to follow-up quickly. You've mentioned $100 million backlog in transmission. I don't know if you expect that to grow at all or whether that was current or exiting fiscal Q3 and the expectation is that that's likely to ship in the calendar second half?
Alan Lowe -- President and Chief Executive Officer
Yes. So sorry, I wasn't clear. The $100 million backlog in transmission is backlog we have today that will not be satisfied by the end of June. So we're going to satisfy a lot of the backlog we have today, but this won't be satisfied.
So if you look back on our historic transmission business, it's usually a $100 million to $120 million a quarter and growing. And with some of the discontinued products that's kind of ebbs and flows, but -- so we have strong backlog. We're continuing to get bookings. And so we're going to end the fiscal year with a very strong backlog, it's my projection.

The next question is from Christopher Rolland with Susquehanna International. Your line is open.
Christopher Rolland -- Susquehanna International Group -- Analyst
Hey guys. Thanks for the question. So on a prior question that you discussed, you've talked about sets of LiDAR world-facing product ready to go. I guess my question is, has this passed the full qualification process at your customer? And then secondly, just regarding a date, and I know it's difficult, I know you guys are waiting, but isn't there some kind of drop-dead date in which you need to implement and plan for capacity to ultimately seize that order? Thank you.
Alan Lowe -- President and Chief Executive Officer
Well, I mean we said we were ramping production of the world-facing LiDAR product in Q3. You don't ramp unless you qualify it. And so product announcements have been made with this product in it. So it's being sold out to consumers.
So I think that the -- we're off and running on that one and we will continue to ramp. As far as the drop-dead date is concerned, we are ready in inventory at the right positions. There's not a -- our customer and -- our main customer and our sales team and product team is very well aligned on when we need to go based on their schedule. So I'm not so worried about a drop-dead date from that perspective.
We'll be ready. And I think we're in a great position relative to our competitors.

Our final question is from Richard Shannon with Craig-Hallum. Your line is open.
Richard Shannon -- Craig-Hallum Capital Group -- Analyst
Well thanks guys. I just have one to finish up here again on 3D sensing. You've talked -- a lot of the answers on that topic I think have been aimed largely at your big customer. Maybe, Alan, if you could talk about the impact on your kind of your Android customers impact from COVID here in terms of time frame as well as even implementation of either front-facing or more specifically world facing? Thanks.
Chris Coldren -- Senior Vice President of Strategy and Corporate Development
Richard, this is Chris. So Android business in the quarter was a bit rough. As you can imagine, smartphone production in China was down quite a bit. So we saw the Android revenues slow considerably quarter on quarter.
With that said, our design in activity and product positioning with Android customers is good and continuing to improve as we have a broad range of products for front and world-facing that satisfy the Android customer needs. And that's one of the advantages of the scale that we have in the business is our -- in a sense, R&D capacity to be able to customize and develop products for all of the customers in the Android space in addition to our largest customer. So we anticipate the Android -- from a design in standpoint, to continue to progress to a broader set of models and higher volume products. I think, as Alan highlighted, it's a little difficult to handicap the overall smartphone volumes in the world over the coming year given [Audio gap]
