Cable Labs: Interoperable 200-Gig coherent optics via Point-to-Point Coherent Optics (P2PCO) 2.0 specs
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.”

MediaTek to expand chipset portfolio to include WiFi7, smart homes, STBs, telematics and IoT
Taiwanese fabless chipmaker MediaTek is gearing up to expand its customer base beyond the increasingly saturated smartphone segment to include connected devices for smart homes, electric vehicle (EV) manufacturers and the smart retail field.
Chunyan See, Thailand country manager for MediaTek, said the company is offering chipsets beyond the smartphone segment to WiFi 7-linked products, set-top boxes (with video streaming so popular aren’t STBs a thing of the past?), telematics, and Internet of Things. Some market leaders and mobile operators plan to launch WiFi 7 products in the first quarter of 2023. Mediatek previously announced chipsets for WiFi 6 and 6E.
“We see the gaps to change from WiFi 6 to WiFi 6E and WiFi 7 becoming shorter and shorter,” said Mr See. “Service operators typically take one to 1.5 years for internal testing to get the requirements finalized.”
Demand for higher wireless connection speed in Thailand is pushing local mobile operators to aggressively invest in 5G and fixed broadband services, he said. With rising inflation and a weaker baht, the overall smartphone market in Thailand will be tough this year, with the market size expected to drop to 19.2 million units, from 20-21 million last year, he said. In the second half of this year, 5G-enabled smartphones are expected to account for 40% of the total market, versus 32% in the first half and 24% in 2021, said Mr See.
MediaTek is also working with local partners beyond the smartphone segment in three fields — smart homes, smart retail, and smart logistics. For smart homes, the company will power the next generation of smart home accessories, including smart lighting and sensors. In smart retail, the firm supports smart point-of-sale devices that can cater for face payments, which is already the norm in China. Regarding smart logistics, 5G equipment powered by the firm’s chipsets can play a key role in telematics, which is a method of monitoring vehicles and other assets by using GPS technology, and can serve EVs. Chinlin Low, technical account manager for Asia-Pacific at MediaTek, said.
ASEAN (Association of Southeast Asian Nations) is expected see a compound annual growth rate (CAGR) of 83% for 5G subscriptions from 2021 to 2027, when they are forecast to reach 570 million.
Mobile data traffic per smartphone is expected to reach 45 gigabytes per month in 2027, up from 9.4GB in 2021, with a CAGR of 30%, driven by the rise of virtual and augmented reality services.
MediaTek has a broad range of chipsets to offer, including Dimensity 9000, 8100 and 8000 to cater for premium smartphones, he added.
Daniel Lin, MediaTek’s deputy director of corporate sales and emerging markets, said the company sees an opportunity to increase its share of the global premium smartphone segment. “MediaTek has a strong market share in smartphones costing between US$99 to $299, but the firm aims to increase its share in premium smartphones with the launch of new chipsets,” he said.
In 2021, the firm’s overall market share in the smartphone segment rose to 42%, from 32% in 2020. Its share in Android-powered handsets surpassed 50% in 2021, up from 38% in 2020.
MediaTek posted revenue of $17.6 billion in 2021, up from $10.9 billion a year earlier.

Neos Networks and Giganet partner to deliver FTTP to millions of UK homes
Dark Fiber network operator Neos Networks has announced a new partnership with Giganet, aiming to support the ISP’s burgeoning FTTP rollout with backhaul and data centre services.
Giganet currently offers customers access to its gigabit services through a variety of network providers, including Openreach and CityFibre, reaching millions of homes across the UK. In fact, earlier this year, Giganet announced that they had extended their partnership with CityFibre, thereby making their services available to customers across the entirety of CityFibre’s UK network.
However, last year Giganet announced they would also be rolling out their own FTTP network directly, investing £250 million to cover underserved areas of Hampshire, Dorset, Wiltshire, and West Sussex.
In total, the company hopes to reach 300,000 premises with full fibre over the next four years, with its core network and first four exchange rings set to be live by the end of 2022.
As this new network grows, it will need additional backhaul capacity and support – something that Neos, with its 550 unbundled exchange network, is well positioned to provide.
“Neos Networks rose to the challenge of providing us with resilient and high capacity backhaul circuits across a wide range of exchanges as well as our core data centres,” explained Matthew Skipsey, Chief Technology Officer at Giganet. “Using Neos Networks, we have been able to secure connectivity to our points of presence faster than expected, initially enabling each of our first four regional rings with resilient 100Gb/s backhaul. This means our south coast roll-out is progressing at pace.”
This network expansion project will see Neos support Giganet to deliver a more than tenfold capacity increase.
“Both Neos Networks and Giganet have adopted a collaborative approach to this relationship. This has resulted not only in solutions being delivered faster than ever, as the Giganet network grows, it also gives us the ability to transition connectivity between points of presence without any disruption,” explained Sarah Mills, Chief Revenue Officer at Neos Networks. “There is no doubt that by working in partnership with alternative network providers, like Giganet, UK residents will benefit from a better, faster, and more resilient connectivity.”
Matthew Skipsey added: “The ready availability of high-quality resilient connections to our points of presence, undoubtedly enabled us to quickly roll-out hyperfast, full broadband to a marketplace hungry for improved connectivity.”

Bloomberg: Chip Sales to Slow Further as Global Recession Fears Mount
Semiconductor sales are set to grow more slowly than previously expected as the international economy struggles under the weight of rapid interest-rate increases and rising geopolitical risks, fueling fears of a global recession. That will adversely effect telecom equipment and handset vendors that depend on advanced semiconductors to build their products.
World Semiconductor Trade Statistics, a non-profit body that tracks shipments, lowered its market outlook to 13.9% growth this year from a previous 16.3%.
In 2023, it sees chip sales rising just 4.6%, the weakest pace since 2019.
The semiconductor market is still expected to surpass $600 billion this year, WSTS says. Next year’s forecast growth would be the weakest since a 12% drop in sales at the height of the U.S.-China trade war.
Chip sales are an important indicator of global economic activity as households and firms increasingly rely on digital devices and online services to consume and expand. President Joe Biden this month signed the so-called CHIPS and Science Act aimed at strengthening the U.S. semiconductor industry as China races to expand its own chip-making capacity. Semiconductor Manufacturing International Corporation (SMIC) is a partially state-owned publicly-listed Chinese pure-play semiconductor foundry company. It is the largest contract chip maker in mainland China and 5th largest globally behind TSMC, Samsung, United Microelectronics Corporation, and GlobalFoundries.
The International Monetary Fund (IMF) last month downgraded its global growth forecast and said 2023 may be tougher than this year. A Bloomberg Economics model sees a 100% probability of a US recession within the next 24 months.
Based in Morgan Hill, California, WSTS includes among its members Texas Instruments Inc., Samsung Electronics Co., Sony Semiconductor Solutions Corp and Yangzhou Yangjie Electronic Technology Co., according to its website.

Nokia and Safaricom complete Africa’s first Fixed Wireless Access (FWA) 5G network slicing trial
Nokia today announced that it has successfully piloted its 4G and 5G Fixed Wireless Access (FWA) network slicing with mobile operator, Safaricom on its live commercial network. This is the first-time 4G/5G network slicing has been successfully achieved in Africa. The trial utilized a multi-vendor network environment and included RAN, transport and core as well as software upgrades to a range of Nokia’s products and services.
The successful trial demonstrates that Safaricom is now poised to support new types of enterprise network services, including fast lane internet access and application slicing. In addition, Nokia is enabling secured FWA slice connectivity to enterprise locations, as well as to private or public application clouds.
The multi-vendor pilot which took place in Kenya’s Western Region, strengthens the strategic partnership between the two companies, with Nokia already providing a wide variety of services and solutions. The pilot demonstrated a number of solutions including Nokia’s AirScale 4G/5G base stations, the NetAct network management and assurance system and Nokia’s FastMile 4G/5G CPE.
Network slicing (which requires a 5G SA Core Network) enables operators the ability to divide a network into multiple virtual slices, which can be optimized for a specific target application or service. The end user of each network slice can then be serviced with different priorities, routing, levels of network performance and security capabilities. Slices can be managed and deployed in minutes, and each one has key performance indicators used for service assurance.
Nokia’s 4G/5G network slicing solution (SORRY, no such thing as 4G network slicing), which received a prestigious award from GTI 2021 in the ‘Innovative Breakthrough in Mobile Technology’ category, supports LTE, 5G NSA and 5G SA technologies with slice service continuity between the networks. This enables slicing services for all LTE and 5G devices.
James Maitai, Network Director, Safaricom, said: “We are proud to have hosted Africa’s first successful pilot of 4G/5G FWA slicing on our network, and looking forward to tailoring our service offerings to individual customers and industries, to meet their needs for high-speed connectivity precisely and without unnecessary cost. Nokia’s expertise has been key to this success, and we anticipate many more strategic wins in this area as our business expands.”
Ramy Hashem, Head of Safaricom Customer Team at Nokia, said: “It is great to have successfully completed this pilot with Safaricom, which is a huge step forward in providing Safaricom with state-of-the-art connectivity. Early experience of new slicing technology is invaluable in understanding the new business opportunities it enables. Nokia was the first vendor to offer a slicing solution and we are looking forward to continuing our partnership with Safaricom in providing world-class 4G and 5G network slicing services to its customers.”

China’s telecom sector had steady growth during January-May 2022 (Updated)
China Mobile and ZTE complete commercial trial of optical network co-routing detection
ZTE and the Yunnan Branch of China Mobile have completed the commercial trial of co-routing detection in China Mobile’s existing optical network in Yunnan Province, China.
The trial involves two scenarios: co-cable routing detection and co-ditch routing detection. The trial result shows that there will be an early warning of active/standby paths in the same optical fiber or route so that it can be avoided in time based on fiber sensing. Besides, the originally dumb fiber resource will be visualized. Thus, the operator’s service reliability and network O&M efficiency can be greatly improved.
As digital transformation is developing rapidly in all industries, the optical network is facing intelligence challenge. Intelligent OA&M emerges as one of the focus areas, while the problem of low service survivability caused by co-routing becomes serious.
China Mobile cooperated with ZTE to verify the feasibility of co-cable and co-ditch routing detection of service paths on the existing optical network, including active/standby service routing detection and inbound/outbound service route detection at specific sites.
According to the verification, ZTE’s optical network co-routing detection function can exactly detect co-cable routing of 14 optical cables and 54 fiber cores by dynamic parameter optimization, AI algorithm and experience threshold adjustment. Also, ZTE takes analysis, contrast and on-site specialist inspection to exactly detect co-ditch routing of 12 optical cables and about 20 ditches in 4 core equipment rooms. The verification proves that ZTE can provide the operator with flexible optical network co-routing detection methods, along with real-time, accurate and reliable intelligent O&M measures, which well guarantees service survivability and alleviates the difficulty in dumb fiber resource management.
“The function can effectively solve actual problems in production and operation. Before this, active/standby routes are planned on the resource management map, and routing is determined manually, which leads to high error rate. Additionally, the accuracy of resource management information is hardly under control, thereby increasing routing risks,” said the leader of Network Management Center of China Mobile Yunnan.
“In the original routing detection, people pulled or pushed the cable underground manually, which resulted in low efficiency and service interruption. However, the co-routing detection now leverages dumb fiber resources without service switching. The innovative function remarkably reduces manpower and ensures service survivability while allowing resource management information modifications and route re-planning to avoid service interruption losses,” he added.
The trial will further promote the growth of the operator’s autonomous optical network and lay a strong foundation for its intelligent network in the “east-data-west-computing” project. Moving forward, ZTE will continue in-depth research and exploration on autonomous optical networks, and work together with global operators to build new intelligent networks to boost the development of digital economy.
This announcement comes just six days after ZTE said that it has ranked No.1 with a share of 50% in China Mobile’s centralized procurement 2022-2023 of Optical Transport Network (OTN) devices. ZTE’s selected devices will help the operator increase the coverage and bandwidth of its provincial networks to satisfy all-optical network development in the era of computing-network convergence.
This centralized procurement involves provincial backbone, core, aggregation and access, covering all network layers in the provinces. AIso, it imposes high requirements upon device types, transmission performance, and cross-connect capabilities.
At provincial backbone, core and aggregation layers, ZTE’s OTN products provide a single-device cross-connect capacity of up to 64T and a single-fiber capacity of up to 96T. With industry-leading 200G/400G transmission performance, they can provide sufficient network bandwidth for new service growth of China Mobile in the 5G era. At the access layer, ZTE’s compact OTN products based on the ODUk/PKT/VC/OSU unified cross-connect platform can provide access of various services such as 4G/5G/home broadband/enterprise network/edge cloud, significantly decreasing operator’s CAPEX and OPEX.
According to the latest assessment released by GlobalData, ZTE maintains the “Leader” rating in “Core Packet-Optical Transports”, with the “Leader” ratings in “cross-connect capacity and functions” as well as “port capacity”. Also, ZTE is rated as “Very Strong” in “Packet-Optical Access” assessment. In addition, ZTE has received high scores from Lightwave Innovation Reviews in February this year.
Moving forward, ZTE will adhere to technological innovation, step up product R&D, and work with global operators to build new intelligent optical networks and boost the digital transformation of the entire industry.
