With the increasing demand for higher bandwidth and better performance, the world’s leading Internet Exchange (IX) operators DE-CIX, LINX, AMS-IX & BCIX, will be introducing a new generation of optical transceivers, the 100G LR-1 (referred to as LR), to their platforms, starting in Frankfurt, London, Amsterdam, and Berlin.
While the existing 100G LR-4 uses four lasers, each carrying a signal of 25 Gbps, the new 100G LR technology uses only a single laser and uses pulse amplitude modulation (PAM4) to transmit data at 100 Gbps. The reduction in transceiver design complexity of the increasingly deployed 100G LR technology will result in power savings as well as better transceiver pricing. These advances not only provide advantages in the short to mid-term but will also unlock new transceiver form factors that open up the potential for even greater performance and efficiency improvements in the future. The 100G LR technology is already available with a wide range of compatible routers from all major vendors and is compatible with current fiber technology. In order to satisfy today’s customer demand for 100G LR, DE-CIX, LINX, AMS-IX, and BCIX will provide support in the upcoming months.
“With the new 100G LR technology, we are paving the way for the next generation of transceiver technology that will dominate the market for years to come. The future design of our DE-CIX interconnection platform will not only bring better programmability and higher scalability, commercial flexibility, and wider geographical reach, it will also make interconnection even easier for our customers through simplified technical processes,” says Dr. Thomas King, Chief Technology Officer at DE-CIX.
Richard Petrie, CTO at LINX stated, “For LINX, we will be enabling our London locations first after approving the solution in our lab. We will roll out as demand grows and as we see that LINX members need support in the shift to the improved optics. This will realise both benefits in cost and power for us and the LINX member base.”
Ruben van den Brink, CTO at AMS-IX says, “Offering 100G LR makes perfect sense, both for AMS-IX and for its customers. The lab tests proved that the new optics can be used for all the switches that are currently deployed in our Amsterdam PoPs. I appreciate the fact that we were able to collaborate with our partners in pushing this new standard. When Internet Exchanges join efforts, customers benefit, so I hope many more exchanges will start offering 100G LR soon.”
“After testing 100G LR and other 100G single-lambda standards in our lab, we have already introduced this new technology into our production network. By doing so we have built a very cost-efficient interconnection between data centers on the same campus. Offering the same benefits to our peers is just the next logical step,” says André Grüneberg, CTO at BCIX.

The optical communications industry entered 2020 with very strong momentum. Demand for DWDM, Ethernet, and wireless fronthaul connectivity surged at the end of 2019, and major shifts to work-at-home and school-at-home in 2020 and 2021 due to the COVID-19 pandemic created even stronger demand for faster, more ubiquitous, higher reliability networks. While supply chain disruptions continued, the industry was able to largely overcome them, and the market for optical components and modules saw strong growth in 2020-2022, as shown the figure in below.
We believe the optical transceiver market will be down slightly (1% or so) in 2023 due to declines in the sales of Ethernet and wireless fronthaul transceivers of 10% and 30%, respectively, offsetting growth in all other market segments in 2023.
Amazon and other cloud companies plan to moderate their investments in 2023 and beyond, even if there is no economic recession. The Cloud companies benefited from the COVID-19 pandemic, but they were forced to reassess their plans at the end of 2022, as growth slowed. Their capex almost doubled between 2019 and 2022 but future investments will be more conservative. We expect the Top 15 ICP’s capex to be up only 4% in 2023, essentially flat, after several years of double-digit growth. Investments in AI infrastructure will remain a priority.
Telecom service providers plan to reduce their capex in 2023 also but they will continue to upgrade access networks. Connecting business and consumers to the Cloud is a priority now. Their customers are willing to pay more for secure and low-latency broadband services and it is a great opportunity for revenue growth. Telecom service providers plan to digitize their operations and offer Network-as-a-Service (NaaS) to an increasing number of end users, not just a few of their largest customers.
Despite a slower than expected growth in revenues of the leading Cloud companies, AI infrastructure remains a priority. This new focus will sustain the market for high bandwidth and low latency Ethernet and InfiniBand switches in the next 5 years. We also expect the deployments of optical circuit switches in AI clusters to expand beyond Google’s datacenters.
Other notable forecast changes include increased sales of 50G and 100G fronthaul transceivers in the 2026-2028 timeframe, as we believe they will be needed for early 6G deployments, and increased sales of PON optics as deployments of FTTx are increasing due to government stimulus in the US and elsewhere.
LightCounting’s Market Forecast Report presents our forecast for optical transceivers used in the telecom and datacom sectors, and includes chapters reviewing the health and spending outlook for both CSPs and ICPs, as well as explanations of forecast drivers and assumptions for each of the six product segments covered: Ethernet, WDM, Fronthaul, Backhaul, FTTX, and Optical Interconnects.

Adtran®, Inc., a leading provider of open and disaggregated networking solutions, today announced that its latest coherent innovation is being showcased at OFC 2023, as part of OFCnet. The demo reveals how the Adtran FSP 3000 open line system (OLS) can bring new levels of flexibility to optical networks by enabling optimized, tailored spectrum services. In collaboration with Acacia, Cisco, Coherent Corp., Corning, EXFO, Nokia and VIAVI Solutions, Adtran will showcase 100ZR, 200Gbit/s, 400Gbit/s OpenZR+ and 800Gbit/s connectivity. The FSP 3000 DCI OLS is also playing a key role in the OIF 400ZR demo at OFC.
“Our demo shows how the spectrum-as-a-service concept has the potential to revolutionize the way operators utilize their fiber resources. It highlights how it’s possible to slice up the network even in a metro environment. With fully flexible spectrum allocation, operators can provide a wide variety of differentiated services and ensure they leverage the full capacity of their infrastructure. Not only will this help tackle ever-increasing data demand, but it also offers a new route to revenue growth. Our compact FSP 3000 OLS is the key to realizing the full benefits of this open and flexible approach. It removes the limits of fixed channel grids so that untapped spectrum can be put to work,” said Jörg-Peter Elbers, head of advanced technology at Adtran.
Adtran also demonstrated its QSFP28 pluggable Coherent 100ZR [1.], which provides 100G coherent edge network connectivity. There was a live display of a 100ZR QSFP28 pluggable operating over a DWDM metro ring. The objective was to show how fiber based network operators can benefit from efficient and cost-effective deployment of coherent 100Gbit/s services with minimal power consumption and low footprint increase. The trial uses the multi-vendor OFCnet network setup with equipment at the Adtran booth as well as the Coherent and OFCnet booths.
Note 1. In June 2022, transceiver developer II‐VI Incorporated (now Coherent Corp.) and optical networking solutions provider ADVA (now owned by Adtran) announced the launch of the industry’s first 100ZR pluggable coherent transceiver. A recently released Heavy Reading survey (see pie chart below) revealed that over 75% of network operators surveyed believe that 100G coherent pluggable optics will be used extensively in their edge and access evolution strategy. However, this interest had not really materialized into a 100ZR market because no affordable or power-efficient products were available. The most the industry could offer was 400ZR pluggables that were “powered-down” for 100G capacity.
Adtran’s Coherent 100ZR is purpose-built for the optical network edge. With its QSFP28 form factor and power specification, it enables easy and cost-effective upgrades to 100Gb/s data rates by plugging directly into existing head-ends, switches and routers. Co-developed by Adtran and Coherent, the DSP offers a range of deployment options, from local exchanges and central offices to harsh outdoor conditions such as street cabinets. These benefits are achieved thanks to the transceiver‘s features, which include a cost-, space- and power-optimized DSP specifically engineered for 100ZR. Adtran is also developing low-power silicon photonics integrated circuits that will enable faster and more energy-efficient solutions across a wide range of applications.
Saeid Aramideh, VP of Business Development at Optical Engines, Adtran said: “This demo is a significant milestone for network operators looking to expand their business capabilities. It highlights how our Coherent 100ZR can be easily and affordably integrated into a metro aggregation network, eliminating the need for costly infrastructure changes. This showcase reveals a valuable solution for operators seeking to support higher data rates at the network edge and highlights the potential for widespread adoption of 100Gbit/s coherent technology. We can’t wait to bring these benefits to our customers.”
Ross Saunders, GM of Optical Engines, Adtran said: “The technology we’re showcasing here will be a game-changer for service providers. It offers the ability to easily deploy coherent 100Gbit/s connectivity with compact footprint and lowest power consumption. By bringing coherent technology to the optical edge, we’re providing operators with a cost-efficient solution to upgrade edge aggregation networks to 100Gbit/s. Our Coherent 100ZR will also boost sustainability by lowering our customers’ carbon footprint. What’s more, it offers a way to deliver an improved experience for end-users by supporting higher data rates and improved service reliability.”
According to a recent Heavy Reading survey, 75% of operators believe that 100G coherent pluggable optics will be used extensively in their edge and access evolution strategy. However, market adoption has yet to materialize since affordable and power-efficient 100ZR-based products are currently not available due to stringent size and power consumption requirements that cannot be fulfilled by today’s tunable laser solutions.
Distribution of responses to a Heavy Reading survey question: How important are 100G coherent pluggable optics for your edge/access evolution strategy? The sample was composed of 87 people who work for network operators worldwide and are involved in network planning or purchasing network equipment.

Additionally, Broadcom in collaboration with Semtech and Keysight will demonstrate a 200G per lane (200G/lane) optical transmission link leveraging Broadcom’s latest SerDes, DSP and laser technology. These demonstrations will be in Broadcom Booth 6425 at the Optical Fiber Communication (OFC) 2023 exhibition in San Diego, California from March 7th to 9th.
“This first-to-market highly integrated 5nm 100G/lane DSP PHY extends Broadcom’s optical PHY leadership and demonstrates our commitment to addressing the stringent low power requirements from hyperscale data center and cloud providers,” said Vijay Janapaty, vice president and general manager of the Physical Layer Products Division at Broadcom. “With our advancement in 200G/lane, Broadcom continues to lead the industry in developing next generation solutions for 51.2T and 102.T switch platforms.”
“By 2028, optical transceivers are projected to account for up to 8% of total power consumption in cloud data centers,” said Bob Wheeler, principal analyst at Wheeler’s Network. “The integration of TIA and driver functions in DSP PHYs is an important step in reducing this energy consumption, and Broadcom is leading the innovation charge in next-generation 51.2T cloud switching platforms while also demonstrating a strong commitment to Capex savings.”
Broadcom has begun shipping samples of the BCM85812 to its early access customers and partners. Please contact your local Broadcom sales representative for samples and pricing.
Separately, Semtech Corp. with Broadcom will demonstrate a 200G per lane optical transmission link that leverages Semtech’s latest FiberEdge 200G PAM4 PMDs and Broadcom’s latest DSP PHY. The two companies plan to recreate the demonstration this week at OFC 2023 in San Diego in their respective booths. Such a capability will be useful to enable 3.2-Tbps optical modules to support 51.2- and 102.4-Tbps switch platforms, Semtech points out.
The two demonstrations will leverage Semtech’s FiberEdge 200G PAM4 EML driver and TIA and Broadcom’s 5-nm 112-Gbaud PAM4 DSP platform. Instrumentation from Keysight Technologies Inc. will verify the performance of the links.
“We are very excited to collaborate with Broadcom and Keysight in this joint demonstration that showcases Semtech’s 200G PMDs and their interoperability with Broadcom’s cutting-edge 200G/lane DSP and Keysight’s latest 200G equipment,” said Nicola Bramante, senior product line manager for Semtech’s Signal Integrity Products Group. “The demonstration proves the performance of a 200G/lane ecosystem, paving the way for the deployment of next-generation terabit optical transceivers in data centers.”

Optical transceivers save space and reduce the need for additional transmitting and receiving devices because they transmit and receive information all in one device! Additionally, they are an economical, compact tool to enable networks to send information over larger distances, come in a variety of Ethernet speeds from Fast Ethernet to 100 Gigabit Ethernet, and offer great flexibility to grow your network while leveraging existing network devices and infrastructure.
Many newer, high quality Small Form-factor Pluggable (SFP) modules have Diagnostic Monitoring Interface (DMI), which automatically monitors SFP operations such as output and input power, temperature, and supply voltage in addition to providing multimode, single mode, and multi-rate SFP options for more flexibility.
Market Research Future® (MRFR) predicts that the global optical transceiver market will rise to 8 billion in the U.S. by 2023.
400ZR coherent pluggable optics emerged as a connectivity tool for metro-distributed data center connectivity. In 2023, look for three additional innovations to enable even more opportunities for coherent pluggables.
High-performance pluggables with 0 dBm transmit power and low out-of-band noise will enable coherent pluggable transceivers to cover a richer set of use cases, including deployment in metro networks with multiple cascaded ROADMs. This increased transceiver performance will also push some pluggables beyond the 600-km metro threshold and into a portion of the long-haul network.
Advances in intelligent pluggables management, as being defined in the 28-member Open XR Forum and with inputs to other organizations like the OIF, will ease deployment complexity and enable operational support for advanced functionality like remote diagnostics, auto-discovery, spectrum analysis, and streaming telemetry in all types of non-optical hosts, including switches and routers.
A new class of coherent pluggables, such as Infinera’s ICE-XR with digital subcarrier technology, will enable commercial deployment of point-to-multipoint architectures, where a single high-speed (e.g., 400G) hub optic can communicate with multiple lower-speed (e.g., 25G to 100G in 25G increments) optics without requiring intermediate electrical aggregation – thus reducing the amount of equipment, space, and power utilized and the total cost of network ownership by up to 70% over multiple years.
Heavy Reading’s optical networking analyst Sterling Perrin sees “pluggable optics everywhere” being a dominant theme. “This includes the continuing trends in 400ZR and ZR+ but also a big focus on migrating down to small coherent 100G pluggables, pluggables across 5G XHaul networks, and pluggables in PON,” he writes in a note to Light Reading.
Data center transmission:
In 2023, look for modular, distributed data center deployments to accelerate, along with 400 Gb/s, 600 Gb/s, and 800 Gb/s per wavelength coherent optical connectivity to support their interconnection
Modular data centers, where construction and integration tasks are moved offsite and then shipped and assembled onsite, are becoming mainstream and enabling compute and storage to be quickly and reliably deployed in all types of settings – from just a few racks in a small hut to megawatts of equipment in a multi-story configuration. In 2023, look for modular, distributed data center deployments to accelerate, along with 400 Gb/s, 600 Gb/s, and 800 Gb/s per wavelength coherent optical connectivity to support their interconnection.
Lisa Huff, Omdia’s senior principal analyst covering optical components will keep an eye out for whether 800G and 1.6T transmission will show up next in data centers. “We are in the middle of 400G deployment inside the data center and, as always, there is much hype around what the next data rate will be,” she writes.
“Omdia expects to see 2x400G and 8x100G solutions start to be deployed inside the data center in 2023, but we will not see high-volume deployment until about 2025 when DR4 and FR4 variants mature and 400G starts to slow down,” she writes. Deployments of 1.6T may start in 2026, but Huff said it might be 2027 or later before we see significant volume.
Omdia Senior Principal Analyst Timothy Munks said that with data traffic growing at the network’s edge, network operators are looking for better solutions to collect and move that data into metro and core networks.
“The convergence of IP and optical, or coherent routing, provides cost effective aggregation and transport of diverse traffic streams and offers network operators a pure pay-as-you-grow business model for adding capacity,” he writes.
In this video, Cisco’s Bill Gartner, SVP/GM Optical Systems & Optics, chats with Phil Harvey to discuss their Leading Lights Award and how Routed Optical Networking is transforming infrastructure and the economics of the network.
To understand the future of high speed coherent optics, Heavy Reading launched the Coherent Optics Market Leadership Program with industry partners Ciena, Effect Photonics, Infinera and Ribbon. The 2022 project was based on a global network operator survey, conducted in August, that attracted 87 qualified responses.
Heavy Reading reports that network operators are using or evaluating coherent optics for 400G transport services for both internal and external applications, as well as 100G data rates for the metro edge.
Nearly half of operator respondents in Heavy Reading’s survey will have deployed 400G transport services in their network between now and the end of 2023. But what are their top motivations for offering 400G transport services? Globally, the top driver for 400G services by far is infrastructure optimization for internal networks. This driver was selected by more than two-thirds of operators surveyed and well ahead of the second choice, standardization of router connections.
The data suggests that, for the global audience of operators, there are not that many customers currently that require full 400Gbit/s connectivity. Yet, there is value in grooming internal traffic up to 400G for greater efficiency and lower costs (e.g., fewer ports, lower cost per bit, etc.).
Beyond internal infrastructure, however, the drivers vary significantly by region, particularly when separating U.S. respondents from their Rest of World (RoW) counterparts. 57% of U.S.operators surveyed identified hyperscalers (or Internet content providers) as a 400G service driver — a strong showing and second only to internal infrastructure in the U.S. In contrast, just 31% of RoW operators identified Internet content providers as a top driver.
What are your top drivers for 400G wavelength (or optical) transport services?
High launch power optics are widely seen as essential for 400G+ pluggables in telecom applications, which are typically brownfield networks with lots of ROADM nodes. However, when filtering the survey results to include optical specialists only (i.e., those who identify as working in optical transport), higher launch power is the number one requirement, well ahead of remote diagnostics. It is likely that, at this early stage, optical specialists within operators understand the criticality of this particular technical requirement better than their peers.
What advanced coherent DWDM pluggable features or capabilities do you find most beneficial to your network/operations?
Coherent pluggable optics at 100G have use case priorities which vary significantly based on geographic region, particularly when separating U.S. respondents from their RoW counterparts. For the U.S., extending geographic reach is the top use case, followed by 5G backhaul/midhaul and enterprise connectivity. For RoW operators, however, extending geographic reach is not a priority use case.
When considering 100G coherent pluggables, what do you see as the most common use cases?
Cable Labs: Interoperable 200-Gig coherent optics via Point-to-Point Coherent Optics (P2PCO) 2.0 specs
In a new report, the Dell’Oro Group states that the demand for Optical Transport equipment remained strong in North America during 2Q 2022. In the quarter, the North American market for Optical Transport grew 10 percent year-over-year.
“At this pace, we could be headed for another year of double-digit growth in North America,” said Jimmy Yu, Vice President at Dell’Oro Group. “While we expected another year of North American optical market expansion in 2022, we thought the growth rate could slow a bit after such a strong 2021. However, considering the first-half results and higher than usual backlog held by equipment manufacturers, we think a double-digit rate of growth could occur in 2022. Our biggest concern, however, remains to be the component shortage and supply chain issues that have limited revenue growth for the past couple years,” added Yu.
Additional highlights from the 2Q 2022 Quarterly Report:
- The worldwide Optical Transport market excluding China grew 2 percent in 2Q 2022 and is projected to grow a little over 4 percent in 2022.
- The region with the lowest year-over-year growth rate in the quarter was Asia Pacific due to lower demand in China.
- The system manufacturers with the highest share of North America Optical Transport revenue in the quarter were Ciena, Infinera, Cisco, and Fujitsu. These four vendors held a combined market share of approximately 85 percent. Please see chart below:
The Dell’Oro Group Optical Transport Quarterly Report offers complete, in-depth coverage of the market with tables covering manufacturers’ revenue, average selling prices, and unit shipments (by speed including 100 Gbps, 200 Gbps, 400 Gbps, and 800 Gbps).

Cablecos use of 200-Gig coherent optical signals in their broadband access network progressed following a recent interop event at CableLabs that involved a five suppliers of coherent optical modules.
CableLabs confirmed that equipment and silicon from those players – Acacia (now part of Cisco), Ciena, Fujitsu Optical Components, Lumentum and Marvell – were found to interoperate with the organization’s Point-to-Point Coherent Optics (P2PCO) 2.0 specs [1.]. The number of participants might not be high, but what’s important is that the participants include DSP silicon from multiple manufacturers that represent the majority of the coherent optics industry.
Note 1. The P2PCO 2.0 specs doubled the operating capacity – from 100 Gbit/s per wavelength in the 1.0 specs, to 200 Gbit/s.
Demonstrating interoperability among so many different coherent DSP suppliers bodes incredibly well for network operators as it provides multi-vendor interoperability, which promotes scale and competition.

Cable Labs conducted 100-Gig interops in 2018 and 2019. Those efforts tie into a broader initiative to use coherent optics technologies, typically used for long-haul, metro and submarine networks, to expand the capacity of fiber that’s already deployed on the hybrid fiber/coax (HFC) access network.
The CableLabs specs also describe a new technology called the Coherent Termination Device (CTD), which can be deployed in an outdoor aggregation node.
Matt Schmitt, a principal architect at CableLabs, said the scope of CableLabs’ interoperability efforts focus on the modules on the optical end – basically describing how a transceiver works at the physical layer.
And to help fit the cable network environment, the end of the network using the CTD is made to reside outdoors, rather than inside a facility.
“Almost every other application of coherent that you see, both ends of the link are in facilities,” such as a data center interconnect where many links are densely packed with racks and modules, Schmitt explained. The cable access application of coherent optics might involve one end that does sit at a facility, such as a hub site, with the other end involving the aforementioned field-deployed CTD.
“Those field boxes didn’t really exist when we started this,” he said.
The broader concept is to help cable operators improve the performance of their access network fibers situated between headends and hubs and fiber nodes for a range of use cases, and to do so without getting locked into one supplier.
CableLabs and its partners originally thought this 200-Gig interop would be completed sooner, but it was delayed a bit during the pandemic when travelling and in-person gatherings were limited or non-existent.
But Schmitt said the plus side of that intervening period meant that the interop ended up with wider supplier participation, particularly at the DSP (digital signal processor) level, than it might have otherwise.
Beyond raw capacity, the 200-Gig capability should help to support the new distributed access architecture (DAA), supported by multiple remote PHY or remote MAC/PHY devices, and the cable’s industry’s broader pursuit of delivering symmetrical 10Gbit/s performance to customers on the access network.
Schmitt said 200-Gig technology gets particularly interesting when operators look to support large, high-density areas that are being split into smaller service groups. It might also factor in as operators explore services beyond high-speed data over cable, such as mobile XHaul.
The use of CTDs with pluggable optics is also designed to support a relatively easy upgrade path. If an operator starts with 100-Gig, those modules can be swapped out for 200-Gig modules later.
This point-to-point P2P use case is just one aspect of coherent optics being explored by CableLabs. A separate-but-related coherent PON initiative still uses coherent signaling, but is focused on point-to-multipoint links.
For now, Schmitt said CableLabs doesn’t plan to hold another interop for P2PCO v2.0 products. “It really just worked so well. I’m not sure what more there will be to do in a follow-up interop,” he said.
CableLabs would be open to doing qualification testing for these new P2P coherent products if the market demands it. “Thus far, I haven’t been hearing of a big push for that,” Schmitt said. “I think people have been comfortable with what we’re getting from the interops and doing their own testing to see how it works.” As for next steps, this latest batch of handiwork will be showcased at the 10G Lab at CableLabs, Schmitt said.
Meanwhile, future commercial deployments will be determined by the availability of CPDs and interest form cable operators.
Among suppliers involved in the recent interop, Ciena confirmed that it currently has interoperable, CableLabs-compliant 200G coherent pluggables available as part of the supplier’s WaveLogic 5 Nano coherent pluggable portfolio.
Another factor for adoption will be costs compared to the 10-Gig DWDM tech that’s in use today. Schmitt acknowledges that the first endpoint is going to be greater with coherent technology, since it involves putting a switch or router in the field.
“Where it gets interesting is every time you need to add another device that’s sharing that same fiber run,” Schmitt said.
“With coherent, you have a higher upfront cost, but you’re going to have a much lower slope, because as you add more devices, all you have to do is add a pair of gray (standard) optics modules – very low cost … Where’s that crossover point in terms of number of endpoints? To me, is going to be one of the big deciders on when and how widespread the deployment of this technology gets.”
Cignal AI reports that total revenue for optical components, a category that includes optical transceivers, grew 15% in 2021. Components for datacom optical network applications led the way, growing 27% to account for $4.7 billion of the total $14.5 billion component sales registered for the year within the datacom, telecom, industrial, and consumer markets, the market research firm states in its latest Optical Components Report.
A transition by large cloud service providers and some enterprise network operators toward 400-Gbps transmission helped spur this growth. For example, 1.8 million QSFP-DD and OSFP datacom modules shipped during 2021, most of which were DR4 format. Meanwhile, more than 60,000 400G pluggable coherent modules shipped at the same time, with QSFP-DD ZR devices accounting for the majority.
“The transition to 400GbE is well underway, and pluggable coherent 400Gbps technology is revolutionizing the design of the optical networks that connect datacenters,” said Scott Wilkinson, Lead Optical Component Analyst at Cignal AI. “400Gbps speeds will drive spending and bandwidth growth both inside and outside the datacenter in 2022,” Scott added.
More Key Findings from the 4Q21 Optical Components Report:
- Supply chain difficulties limited Telecom optical components market growth the most in 2021. However, the segment is forecast to grow more than 8% in 2022.
- Consumer component revenue for 3D sensing applications was flat YoY as lower-cost components offset higher unit shipments.
- Industrial optical components used for welding and medical applications grew 18% in 2021, following a weak 2020. Following the acquisition of Coherent, II-VI is poised to control over 50% of this market.
- 1.8M QSFP-DD Datacom modules shipped during 2021, most of which were DR4 format. The report also tracks SR4, FR4, and LR4 Datacom transceivers.
- Over 60k 400Gbps pluggable coherent modules shipped last year, the majority of which were QSFP-DD ZR. The report captures the shipment details of all the emerging derivatives of this format, including ZR, ZR+, 0dB ZR+, and CFP2 based ZR+.
- Shipments of 200Gbps coherent CFP2 modules grew 17% to just over 200k units during 2021 as Chinese OEMs ramp this speed (which is less dependent on western technology) for longer distance metro and long haul applications.
