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:

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.

According to a recently published report from Dell’Oro Group, the Optical Transport equipment market contracted 2 percent year-over-year in the first nine months of 2021 due to lower sales in China. Outside of China, however, the demand for optical equipment continued to increase, outpacing supply.
“Optical equipment revenue in China took a sharp turn for the worse in 3Q 2021,” said Jimmy Yu, Vice President at Dell’Oro Group. “As a result, optical revenue in China declined at a double-digit rate in the quarter, resulting in a 9 percent decline for the first nine months of 2021. At this rate, we are expecting a full year optical market contraction in the country. Something that has not occurred since 2012. Helping to offset some of this lower equipment revenue from China was the robust demand in North America, Europe, and Latin America.”
“We estimate that Optical Transport equipment revenue outside of China grew 6 percent year-over-year in the third quarter. However, we believe this growth rate could have been higher, closer to 10 percent, if it was not for component shortages and other supply issues plaguing the industry. So, fortunately while optical demand is hitting a rough patch in China, it seems to be accelerating in other parts of the world,” added Yu.
The optical transport market is predicted to reach $18 billion by 2025, primarily as a result of demand for WDM equipment, Dell’Oro reported in July 2021. In addition, Dell’Oro says the ZR pluggable optics market could exceed $500 million in annual sales by 2025.
In a 2Q-2021 report by market research firm Omdia, analysts noted that 5G investment, cloud service growth and demand for “infotainment-at-home” are among the drivers increasing demand in the optical networking market. “The twin dynamics of increasing optical capillarity and increasing end-point capacity continue to drive the optical core,” Omdia wrote in a note to clients.

Nokia and Orange announced the completion of a network trial using the Nokia PSE-Vs, its fifth generation super coherent optics. With this field trial, Orange has successfully validated a planned upgrade of its long-haul backbone networks to support new high-bandwidth 400 Gb/sec services, and the ability to scale fiber capacity up to 600Gb/sec. This represents an increase in spectral efficiency by 50% compared to prior technologies on its long distance optical network.
The trial was performed in real-world conditions using Nokia PSE-Vs super coherent optics in production-ready optical transport hardware, just 16 months after the lab prototype trial done on Orange’s live network. Orange and Nokia demonstrated error-free performance at a data rate of 600Gb/sec over a 914 km network between Paris and Biarritz, under challenging live network conditions. The fiber network consisted of 13 spans of Orange’s existing network, through multiple cascaded reconfigurable optical add/drop multiplexers (ROADM), using 100GHz WDM spectrum channels.
Jean-Luc Vuillemin, Vice President of International Networks and Services at Orange, said: “With the booming market bandwidth requirement and need for scalability and flexibility, it is important that Orange continues to support an ever-greater network scale and new high-bandwidth services across our terrestrial and subsea global footprint.
Validating super coherent optics with Nokia represents an important enabler for future-proof networks which will bring spectral efficiency and operational deployment flexibility to our customer solutions. Furthermore this technology will allow for power savings by nearly 50%, which is key to our objective of developing greener networks for our customers. ”
James Watt, Head of Optical Networks Division, Nokia, said: “We are delighted to work with Orange in continued support of their network upgrade plans. With the introduction of the PSE-Vs super coherent capabilities across our entire 1830 portfolio, Nokia enables spectrally-efficient transport at 600Gb/sec over real-world long haul networks, and 400Gbps services over ultra long haul networks spanning multiple 1000’s of kilometers.”
The Nokia PSE-V
The Nokia PSE-V is the industry’s most advanced family of digital coherent optics (DCO), powering the next generation of Nokia high-performance, high-capacity transponders, packet-optical switches, disaggregated compact modular and subsea terminal platforms. The PSE-V Super Coherent DSP (PSE-Vs) implements the industry’s only 2nd generation probabilistic constellation shaping (PCS) with continuous baud rate adjustment, and supports higher wavelength capacities over longer distances – including support for 400G over any distance – over spectrally efficient 100GHz WDM channels while further reducing network costs and power consumption per bit.
Earlier this week, Nokia and Bell Canada announced the first successful test of 25G PON fiber broadband technology in North America at Bell’s Advanced Technical Lab in Montréal, Québec.
The trial validates that current GPON and XGS-PON broadband technology and future 25G PON can work seamlessly together on the same fiber hardware, which is being deployed throughout the network today. 25G PON delivers huge symmetrical bandwidth capacity that will support new use cases such as premium enterprise service and 5G transport. Nokia’s 25G PON solution utilizes the world’s first implementation of 25G PON technology and includes Lightspan and ISAM access nodes, 25G/10G optical cards and fiber modems.
For the past decade, Bell has been rolling out fiber Internet service to homes and businesses across the country, a key component in the company’s focus on connecting Canadians in urban and rural areas alike with next-generation broadband networks. With this successful trial, Bell can be confident that its network will absorb the increased capacity of future technologies and connect Canadians for generations to come.
Stephen Howe, EVP & Chief Technology Officer, Bell, said:
“As part of Bell’s purpose to advance how Canadians connect with each other and the world, we embrace next-generation technologies such as 25G PON to ensure we remain at the forefront of broadband innovation. Our successful work with Nokia to deliver the first 25G PON trial in North America will help ensure we maximize the Bell fiber advantage for our customers in the years to come.”
Jeffrey Maddox, President of Nokia Canada, said: “Nokia innovations powered the fiber networks and the connectivity lifeline that carried Canadian homes and businesses through the pandemic. 25G PON innovations will drive the next generation of advances in our connected home experience.”
Bell and Nokia have closely collaborated over the years on many industry breakthroughs, such as the first Canadian trial of 5G mobile technology in 2016. Bell continues to work with Nokia to build and expand its 5G network across Canada.
Bandwidth growth, driven by the expansion of data centers and 5G network build-outs, is expected to drive the need for faster coherent Dense Wavelength Division Multiplexing (DWDM) pluggable optics. Consequently, Data Center Interconnect (DCI) and metro Optical Transport Network (OTN) platforms are transitioning from 100/200G to 400G pluggable coherent optical modules to support these hyper-connected architectures.
Microchip Technology (a fabless semiconductor company) and Cisco’s Acacia unit are working together to validate the interoperability of their 400G pluggable optics components – Microchip’s DIGI-G5 OTN processor and META-DX1 terabit secured-Ethernet PHY and Acacia’s 400G pluggable coherent optics.
The purpose of the collaboration is to establish an ecosystem to support 400G CFP2-DCO, QSFP-DD and OSFP modules for the 400ZR specification as well as the OpenZR+ and Open ROADM Multi-Source Agreement (MSA) applications.
The collaboration between Microchip and Acacia helps to enable the use of 400G coherent pluggable optics in OTN and Ethernet systems as follows:
- For converged packet/OTN optical platforms, Microchip’s DIGI-G5 and Acacia’s 400G CFP2-DCO module are designed to enable terabit-class OTN switching line cards, mux/transponders, and switch/transponders. The DIGI-G5 interoperates with Acacia’s 400G CFP2-DCO module using a Flexible OTN (FlexO) or NxOTU4 interface to efficiently support OTN traffic, including Open ROADM MSA interface modes and 200G/400G ITU-T standards currently being drafted.
- For compact modular optical systems, Microchip’s META-DX1 and Acacia’s 400ZR and OpenZR+ modules are designed to enable 400G flexible line rate muxponders/transponders with support for multiple client optics types including QSFP28, QSFP-DD, and OSFP modules, helping service providers to transition from 100 GbE to 400 GbE using the same hardware.
- For data center routing and switching platforms, Microchip’s META-DX1 and Acacia’s 400ZR and OpenZR+ modules are designed to enable dense 400 GbE or FlexE with per port MACsec encryption coherent line cards. This helps customers leverage IP routers/switches over DWDM (IPoDWDM) infrastructure in DCI deployments.
“DIGI-G5 and META-DX1 have enabled our optical transport, IP routing and Ethernet switching customers to implement a new class of multi-terabit OTN switching and high-density 100/400 GbE and FlexE line cards that deliver on stringent packet timing and integrated security capabilities for the build out of cloud and carrier 5G-ready optical networks,” said Babak Samimi, vice president for Microchip’s Communications business unit. “Our interoperability efforts with Acacia help to demonstrate that an ecosystem for volume deployment of these new line cards with pluggable 400G coherent optics exists.”
“With Acacia’s 400G coherent modules verified to interoperate with Microchip’s DIGI-G5 and META-DX1 devices, we see it as a robust solution designed to address network capacity growth and improved efficiency,” said Markus Weber, senior director DSP, product line management of Acacia, now part of Cisco. “The compact size and power efficiency of our 400G OpenZR+ CFP2-DCO modules were designed to help network operators deploy and scale capacity of high-bandwidth DWDM connectivity between data centers and in metro networks.”
Kevin So, associate director of product line management and marketing at Microchip, told Fierce Telecom that the pair have a history of collaboration that goes back to work on 100G. He said their latest effort is meant to proactively eliminate elements of risk operators face as they begin to upgrade to the latest 400G technology. While most solutions are based on industry standards, So cautioned that’s not always a guarantee that components from different companies will work well together.
“I’ve seen in our industry often standards are written, people think things are going to work and then you show up at a carrier lab and that’s when you discover problems. Standards still do not necessarily always ensure everything is interoperable ready to go, and it can be a barrier for ultimately our customers and service providers in deploying it,” Mr. So said.
The companies stated they successfully validated interoperability between their respective components for 400G, ZR and OpenZR+ configurations in converged packet and OTN optical platforms, compact modular optical systems and data center routing and switching platforms.
So said Microchip’s work with Acacia started in the pre-silicon stage, ensuring the interfaces and designs they were pursuing were compatible. Once the silicon in question became available, the pair “tested these components together as a system to make sure it’s robust enough.”
Tom Williams, director of marketing for Acacia told Fierce Telecom, “This interop testing demonstrates that leading vendors are working together to streamline the integration process. There wasn’t any expectation of issues, but it builds confidence to know that the vendors have already done this work directly.”

During OFC 2021 last week, Ciena and Lumenisity Ltd. said that they had partnered to demonstrate transmission of 45 wavelengths, each at 400G, over 1,000 km of hollowcore fiber cable.
The demonstration paired Lumenisity’s CoreSmart hollowcore cable with Ciena’s WaveLogic 5 Extreme and Nano coherent optical engines, with the transmission occurring in a recirculating loop. The companies say their work indicates that hollowcore fiber cable can be used for high-bandwidth, long-reach applications such as data center interconnect (DCI) in addition to edge and 5G xHaul applications Lumenisity had previously cited (see “Lumenisity, BT drive 400ZR DWDM transmission over hollowcore fiber“ and “BT testing hollowcore fiber for 5G support”).
Lumenisty said that it has been working over the past six months with ecosystem partners to test the CoreSmart low-latency hollowcore cable in its System Lab in Romsey, UK (see “Startup Lumenisity unveils hollowcore fiber cables for DWDM applications, new funding” for more on Lumenisity’s fiber). Ciena participated in at least some of those exercises, including a second trial in which the two companies achieved a capacity of 38.4 Tbps with 48x800G channels over greater than 20 km without in line amplification using the current generation of CoreSmart. Lumenisity says the next generation of CoreSmart will be able to extend reach in such an application to between 50-100 km with no inline amplification when paired with the WaveLogic 5 Extreme.
“The results obtained both internally and with Ciena commercial WaveLogic 5 systems show further evidence that we are bringing our world-class hollowcore fiber cable technology to market at an accelerating rate for multiple high-capacity applications, that solve real world latency issues for our customers,” commented Tony Pearson, business development director at Lumenisity.
“System characterization results of WaveLogic 5 Extreme programmable 800G and WaveLogic 5 Nano 400ZR coherent pluggables running over CoreSmart show promising results with hollowcore fiber now proven to preserve high-capacity while materially reducing latency,” added Steve Alexander, senior vice president and CTO of Ciena. “We are proud to be at the forefront of this breakthrough technological achievement where we can enable a 50% increase in reach for latency-sensitive data center interconnects.”
Separately, CTO Alexander wrote a blog titled, “Ciena has joined Google Cloud’s 5G/Edge ISV Program to help enterprises accelerate migration of their IT resources to the cloud“
Here’s an excerpt:
To facilitate the migration of enterprise IT workloads to the cloud, there is a requirement for higher speed connections from the enterprise edge to cloud provider that are scalable with enhanced security to best protect critical business data. Shared IP network connections to the cloud are acceptable for lower speed (10Gb/s) connections and below. However, when secure, higher speed connections are required to the cloud, connectivity via the IP network can become overly complex, expensive, and inefficient when compared to the optical network (Optical Fast Lane) that can provide a more efficient, cost-effective, and secure option for enterprises needing to reduce their workload migration times to support their evolving business objectives.
For the multi-cloud market to succeed, it must reduce the friction for enterprises to migrate their workloads to a cloud provider, as well as between cloud providers – on demand. This is analogous to the days when you had a mobile plan with one carrier, and to switch to another carrier, you had to switch mobile numbers, which was too complex for most customers, so they stuck with their existing carrier. Only when consumers could keep their phone number when they switched carriers (through Local Number Portability), did it make the mobile market truly competitive leading to improved choice, pricing, and innovation. This is what we’re trying to achieve in the multi-cloud market.
Google Cloud is one of the leading cloud providers in the market that embraces an architecture that enables their enterprise customers to gracefully migrate their workloads to Google Cloud via an Optical Fast Lane that enables Enterprise to develop and leverage the Google Cloud for new and innovative applications. Ciena is excited to be a key player in this program and in addressing this opportunity in the industry. This builds off Ciena’s long standing relationship with Google and other Cloud Providers serving both private and managed high-capacity optical transport networks – principally dominated by subsea, long-haul, metro and DCI connectivity.
Ciena is also a major supplier to Communication Service Providers (CSPs) and MSOs – serving all segments of the network – including high-speed access connectivity for Enterprises as well as cell-site routing and backhaul. In partnership with CSPs, Google Cloud is helping customers leverage their edge real-estate assets to facilitate low latency connectivity to Google Cloud and reduce the friction required for enterprises to improve their mean time to the cloud for their data and workloads.
The premier event in optical telecom—the 2021 Optical Fiber Communication Conference and Exhibition (OFC) concluded last week. The virtual event drew over 6,500 registrants from 83 countries.
“OFC 2021 saw technology announcements and technical presentations spanning the optical communications ecosystem, including advancements in optoelectronic devices, packaging and digital signal processing that are all rapidly evolving to achieve 800G and beyond, as well as those in architectures and algorithms towards more intelligent optical networking,” said Jun-ichi Kani, OFC General Chair, NTT, Japan. “OFC is the only event where attendees can access the full spectrum of trends shaping the industry and the way we connect across the globe.”
Speakers presented breakthroughs in many areas, including 400/ZR+, 800G, co-packaged optics, embedded optics, next-gen optical access, silicon photonics, space-division multiplexing, data center networks, automation and intelligence in networks and more. Sessions on quantum science and technologies, sensor applications and free space optics appealed to a large audience and enriched the OFC experience. Recorded sessions are available to registrants as on-demand content for 60 days following the close of the event.
“OFC is the go-to event for the optics industry,” said Jimmy Yu, vice president, Dell’Oro Group. “From the thought-provoking panel discussions to the product announcements, OFC has always been the place where I learn about emerging technologies.”
Technology experts from global leaders II-VI, Broadcom, Ciena, Cisco, Corning, Innolight, Intel, Juniper Networks, Lumentum, NeoPhotonics, Nokia and Ribbon discussed developments in hardware and software-based networking solutions in daily briefings with leading analysts, Sterling Perrin, Heavy Reading; Ian Redpath, OMDIA; Andrew Schmitt, Cignal AI; Jimmy Yu, Dell’Oro Group and Vladimir Kozlov, LightCounting.

Innovations in Optics
Leading researchers from around the world presented technical peer-reviewed papers, including:
- Trans-Atlantic Real-Time Field Trial Using Super-Gaussian Constellation-Shaping to Enable 30 Tb/s+ Capacity — A team of researchers from Infinera Corporation, USA and Facebook demonstrated a record-breaking transatlantic transmission across MAREA.
- A Latency-Aware Real-Time Video Surveillance Demo: Network Slicing for Improving Public Safety — Researchers presented a latency-aware optical metro network having sophisticated monitoring and data analytics capabilities and discussed the network architecture and enabling technologies, as well as a video surveillance case of the system.
- Demonstration of 100Gbit/s Real-Time Ultra High Definition Video Transmission Over Free Space Optical Communication Links — A team of researchers discussed how they achieved real-time FSO transmission of an ultrahigh-definition video stream between two buildings in Beijing.
- 224-Gb/s PAM4 Uncooled Operation of Lumped-electrode EA-DFB Lasers with 2-km Transmission for 800GbE Application — Researchers at Lumentum showed how they developed an optical solution that uses four 200 Gbps wavelength lanes to reach 800 GbE.
Post Deadline Papers looked to the future with developments in high-speed individual LEDs, modulated lasers, record low loss in hollow core fibers for applications in power delivery and sensing and other topic areas important to industry.
Analysts also revealed their recent findings around the sector to coincide with the event. For instance, Cignal AI suggested there have been strong gains in switching and routing spending by operators in the first quarter of the year, but these were offset by the slightly weaker deployment of optical transport gear.
Scott Wilkinson, lead analyst for transport hardware at Cignal AI, noted that “Chinese spending on optical hardware has plateaued as major 5G network builds mature and new projects have not been initiated.” He added that the country’s “extraordinary growth during 2015 to 2018 could not continue long term due to the impracticality of expanding upon the enormous amounts that had been spent in the region.”
In general, analysts reported subdued activity by Chinese operators across all product categories after last year’s strong growth, while most other territories showed a rebound this quarter.
OFC 2022 will be held 06 – 10 March at the San Diego Convention Center, San Diego, CA.
