Crehan: 400 GbE port shipments to exceed 10 million this year

Shipments of 400 gigabit Ethernet (GbE) data center switch ports are on track to exceed 10 million this year, more than triple the prior year's shipments, according to an upcoming report from Crehan Research Inc. 

In correlation with this strong 400GbE data center switch ramp, 50Gbps SerDes shipments are surpassing 25Gbps SerDes shipments, to become the mostly widely deployed data center switch SerDes lane speed.

“The 400GbE data center switch transition is well under way, with volumes now starting to move toward the tens of millions in conjunction with broader customer adoption,” said Seamus Crehan, president of Crehan Research. “Newer applications and architectures such as machine learning and disaggregated computing, on top of existing high-bandwidth drivers including video, machine-to-machine traffic anddata analytics, are driving the need for faster switch speeds with better bandwidth economics.”

These results reflect the data center switch silicon transition from 3.2Tbps to 12.8Tbps and their respective underlying technologies of 25Gbps and 50Gbps SerDes. Crehan’s report further points out that the 50Gbps SerDes transition time of approximately three years is faster than what the 25Gbps SerDes transition was.

"These large deployments of 12.8Tbps data center switches, with underlying 50Gbps SerDes technology, are laying the groundwork for the deployments of next-generation 25.6Tbps data center switches with 100Gbps SerDes technology, which we expect to start ramping next year," Crehan said.

Openreach awards 3-year contract to Prysmian for full fibre rollout

Openreach awarded a new three-year contract to Prysmian Group to support its updated Full Fibre broadband build plan which will be fundamental to the UK Government achieving its target of delivering ‘gigabit capable broadband’ to 85 per cent of UK by 2025.

Openreach has recently undertaken a live trial using the double overblow installation method developed by Prysmian Group. This Karona installation technique enables the installation of high density optical fibre cable into pre-existing sub-ducted routes, already containing legacy cable. The trial took place at Stonehaven in Scotland. The cable used for the trial was Sirocco HD 144f with 5.0mm diameter, and the innovative installation method allowed to overblow 600mts of cable in less than 4 hours, increasing the capacity of the route to 432f. This installation technique was repeated at Bury St Edmunds, where a route of 730mts was successfully overblown in less than 4 hours.


“Prysmian has been a partner with Openreach for over 50 years. This latest contract reflects the positive impact our working relationship has had on the UK’s digital networks infrastructure,” comments Marcello Del Brenna, CEO Prysmian Group UK. “The extension of our working relationship comes at a time where Prysmian is investing in telecommunications innovation to ensure our digital network partners have the cutting-edge solutions. We have also taken great steps forward with our sustainability effort, eliminating paper inclusions from our products and replacing them with digital solutions.”

Matthew Hemmings, MD for Fibre and Network Delivery at Openreach, said “Building a new broadband network across the UK is a hugely complex, nationwide engineering project – second only to HS2 in terms of investment. It will help level-up the UK because the impact of Full Fibre broadband stretches from increased economic prosperity and international competitiveness, to higher employment and environmental benefits by enabling more home working and fewer commuting trips. ”

MIPI Alliance doubles performance of automotive SerDes to 32 Gbps

The MIPI Alliance completed development work on A-PHY v1.1, the next version of the automotive serializer-deserializer (SerDes) physical-layer interface. 

Version 1.1 will double the maximum available downlink data rate from 16 Gbps to 32 Gbps and include other enhancements to help automotive OEMs and their suppliers implement high-performance image sensors and displays in next-generation vehicles. The specification is undergoing member review, with official adoption expected within the next 90 days.

"A-PHY continues to evolve to meet the ever-increasing demand for high-performance, end-to-end automotive connectivity solutions with high reliability, resiliency and interoperability," said Joel Huloux, chairman of MIPI Alliance. "With unprecedented bandwidth and a growing number of implementation options, A-PHY is positioned to power the development of the next generation of safer, more connected and autonomous vehicles."

MIPI A-PHY is the first industry-standard, long-reach, asymmetric SerDes interface to provide high-performance links between automotive image sensors and displays and their associated electronic control units (ECUs). It was developed to simplify the integration of greater numbers of onboard sensors and displays for applications such as advanced driver-assistance systems (ADAS), digital cockpits, in-vehicle infotainment (IVI) and autonomous driving systems (ADS).

  • A-PHY offers a reach of up to 15 meters, unprecedented reliability with an ultra-low packet error rate of 10-19, high noise immunity and ultra-low latency. It also forms the foundation of MIPI Automotive SerDes Solutions (MASS), an end-to-end framework for connecting cameras, sensors and displays with built-in functional safety, security and data protection.
  • A-PHY v1.1 doubles the total downlink data rate from 16 to 32 Gbps by adding support for Star Quad (STQ) shielded dual differential pair cables that provide dual differential pairs of conductors within a single shielded jacket. This enables two A-PHY ports over a single cable, saving cost, weight and complexity compared with using two separate coaxial or shielded twisted pair cables.
  • Version 1.1 will also add optional PAM4 encoding for A-PHY downlink gears G1 and G2, with data rates of 2 Gbps and 4 Gbps, respectively. PAM4 encoding features lower modulation bandwidth for sub-1 GHz operation, allowing manufacturers to more easily migrate to A-PHY while using either legacy cables on current platforms or lower-cost cables on new platforms.
  • The new version will also add a faster uplink gear with an available data rate of up to 200 Mbps, twice the rate of the existing 100 Mbps uplink gear, providing more bandwidth for command and control of automotive peripherals. A-PHY v1.1 will be fully interoperable with A-PHY v1.0, and devices using both specifications will be able to coexist on the same network.

Optica: Cities are the Key to the Climate Solution

 The Global Environmental Measurement and Monitoring (GEMM) Initiative, an international project of Optica (formerly OSA) and the American Geophysical Union (AGU), is inviting city leaders, policymakers, scientists and the business community to discover how cost-effective technologies for monitoring greenhouse gas (GHG) and air pollution emissions in urban environments can measure and predict the impact of climate policy and planning decisions.

Recent deployments of low-cost, high-density GHG sensors in several cities have yielded initial datasets demonstrating the utility of mapping GHG and air pollution levels in real time. Analyses of the COVID-19 emission reductions show that determining the emission contributions from various source sectors with detailed mapping and timing across the full diurnal cycle is possible and can provide invaluable information on governmental policies affecting GHG emission levels.

NEC to build 24-fiber-pair transatlantic cable for Facebook

NEC has been contracted by Facebook to build an ultra-high performance transatlantic subsea fiber-optic cable connecting the USA and Europe. The project will use NEC’s newly developed 24 fiber pair cable and repeater, enabling the system to deliver a maximum transmission capacity of a half Petabit per second, the highest to date for a long-distance repeatered optical subsea cable system.


Facebook confirmed its first-ever transatlantic, 24-fiber-pair subsea cable system will connect Europe to the United States, buiding on its recent news about 2Africa Pearls, the subsea cable connecting Africa, Asia, and Europe.

Facebook also announced a second generation of its Bombyx robot, which climbs and then install fiber over medium-voltage power lines. The updated design is lighter, faster, and more agile. 

In addition, Facebook's Terragraph radios are now being used to deliver high-speed internet to more than 6,500 homes in Anchorage, Alaska, and deployment has started in Perth, Australia. Facebook licenses Terragraph for free to OEMs who have collectively shipped more than 30,000 Terragraph units to more than 100 service providers and system integrators around the world. 


NEC targets subsea cables to 24 fiber pairs and beyond

NEC and its subsidiary OCC Corporation completed full qualification of subsea repeaters and optical cable containing up to 20 fiber pairs (40 fibers). This represents a 25% improvement in fiber count over 16 fiber pair systems previously built by NEC.

NEC said it achieved this milestone with only minor modifications to its proven repeater and cable designs. This was done by optimizing key repeater components, and by proving that its existing cable design could easily accommodate more fibers. The 20 fiber pair repeaters continue to use quadruple pump sharing technology, first introduced by NEC in 2010, for high optical and electrical efficiency.


OCC’s 20 fiber pair cable can be manufactured using a wide range of existing optical fibers, according to the needs of each new cable system. Furthermore, OCC has demonstrated to its customers that they can visually identify individual fibers using a combination of ring marking and conventional fiber coloring. This allows the potential number of fibers in a cable to be greatly expanded. Significantly, in OCC cable, the fiber’s transmission performance is completely unaffected, either by the fiber coloring or cabling processes.

“As global capacity demand continues to soar, NEC is committed to helping our customers scale up their networks in a cost-effective way,” said Takaaki Ogata, Executive Technical Manager of NEC’s Submarine Network Division. “Further significant increases in the fiber pair count of NEC’s wet plant are coming soon,” he added.

Mass production of the newly-qualified subsea repeaters and optical cable has already started.

2Africa will be longest subsea cable system in the world

The 2Africa cable system will add an extension to the Arabian Gulf, India, and Pakistan, bringing its total length to over 45,000 kilometers, making it the longest subsea cable system ever deployed.  

The 2Africa consortium includes China Mobile International, Facebook, MTN GlobalConnect, Orange, stc, Telecom Egypt, Vodafone and WIOCC.

Now connecting three continents, Africa, Europe and Asia terrestrially through Egypt, 2Africa creates unique connectivity by adding vital landing locations in Oman (Barka), UAE (Abu Dhabi and Kalba), Qatar (Doha), Bahrain (Manama), Kuwait (Kuwait), Iraq (Al-Faw), Pakistan (Karachi), India (Mumbai), and a fourth landing in Saudi Arabia (Al Khobar). The new 2Africa branch joins recently announced extensions to the Canary Islands, the Seychelles, Comoros Islands, Angola, and a new landing to south-east Nigeria.

As with other 2Africa cable landings, capacity will be available in PEARLS landings at carrier-neutral facilities or open-access cable landing stations on a fair and equitable basis, encouraging and supporting the development of a healthy internet ecosystem. 

Alcatel Submarine Networks (ASN) will deploy the new system utilizing new technologies such as SDM that allow the deployment of up to 16 fiber pairs.



2Africa subsea cable boasts design capacity up to 180 Tbps

2Africa, a new subsea cable to serve the African continent and Middle East region, promises to deliver more than the total combined capacity of all subsea cables serving Africa today, with a design capacity of up to 180Tbps on key parts of the system.

Consortium partners include China Mobile International, Facebook, MTN GlobalConnect, Orange, stc, Telecom Egypt, Vodafone and WIOCC.

Alcatel Submarine Networks (ASN) has been selected to build the fully-funded cable. The project will leverage SDM1 (space division multiplexing) technology from ASN, allowing deployment of up to 16 fiber pairs instead of the eight fiber pairs supported by older technologies. The cable will incorporate optical switching technology to enable flexible management of bandwidth. Cable burial depth has also been increased by 50% compared to older systems, and cable routing will avoid locations of known subsea disturbance, all helping to ensure the highest levels of availability.

The 2Africa subsea cable will span 37,000km long, interconnect Europe (eastward via Egypt), the Middle East (via Saudi Arabia), and 21 landings in 16 countries in Africa. The system is expected to go live in 2023/4. Each of the cable landing sites will offer carrier-neutral data centers or open-access cable landing stations on a fair and equitable basis.

In addition, the 2Africa parties and Airtel have signed an agreement with Telecom Egypt to provide a completely new crossing linking the Red Sea and the Mediterranean, the first in over a decade. This includes new cable landing stations and deployment of next-generation fiber on two new, diverse terrestrial routes parallel to the Suez Canal from Ras Ghareb to Port Said, and a new subsea link that will provide a third path between Ras Ghareb and Suez. 

BT and Toshiba to build quantum-secured metro network across London

BT and Toshiba are to build a quantum-secured metro network linking sites in London’s Docklands, the City and the M4 Corridor.  The two companies’ initial focus will be to provide trials for enterprise customers who are carrying sensitive traffic (such as database backups) between sites, and to explore potential future offerings such as encrypted links and “quantum keys-as-a-service."  A timeline has not been disclosed.

BT will provide data services secured using Quantum Key Distribution (QKD) and Post-Quantum Cryptography (PQC) over Openreach’s Optical Spectrum Access Filter Connect (OSA FC) solution for private fibre networks. The QKD links will be provided using a quantum network that includes both core and access components, and will be integrated into BT’s existing network management operations. 

Toshiba will provide quantum key distribution hardware and key management software. The company launched commercial products for QKD, manufactured at its Cambridge site, in the latter half of 2020. Toshiba says it has achieved the highest key rates (1,000’s of keys per second) and longest range of any commercially available fibre QKD system.

While BT and Toshiba have previously installed a point-to-point quantum-secure link between two commercial sites, deploying a full quantum-secured metro network environment with multiple endpoints requires new approaches to integration and management. 

Building on the BT and Toshiba point-to-point solution for the Bristol-based NCC (National Composites Centre) and Centre for Modelling and Simulation (CFMS), this new network will extend the solution to serve multiple customers across the London metropolitan area.  

Howard Watson, CTO of BT, said: “BT and Toshiba have established a global lead in the development of quantum-secure networks. We’re excited to be taking this collaboration to the next level by building the world’s first commercially operational quantum-secured metro network in London. Secure, robust and trusted data transfer is increasingly crucial to our customers across the globe, so we’re proud of the role our Quantum R&D programme is playing in making the world’s networks safer as we enter the dawn of a new age of quantum computing.”

Taro Shimada, Corporate Senior Vice President and Chief Digital Officer at Toshiba Corporation, said: “Our partnership with BT will allow us to offer organisations quantum-secured network services which protect their data from retrospective attacks with a quantum computer. We are delighted to work with BT, with its long heritage of delivering secure, trusted networks. This network paves the way for commercial QKD services in the UK and eventually beyond.”

Frontier accelerates fiber buildout

 Frontier Communications has set a new objective to reach 10 million total fiber locations by the end of 2025. Frontier made significant progress toward this objective in the second quarter of 2021, building fiber to approximately 157,000 new locations. Frontier now expects to reach 600,000 new locations in 2021, resulting in approximately 4 million fiber locations passed by the end of the year.

Nick Jeffery, President and Chief Executive Officer of Frontier, said “Demand for high-speed broadband is growing rapidly, and fiber is the best product to meet the needs of consumers and businesses. Frontier is already doing what customers want and cable can’t – delivering symmetrical download and upload speeds with far lower latency than our competition. Early next year, we will start delivering 2 gigabit per second services, further stretching our performance lead to where only fiber can compete. We have hard work ahead of us, but momentum is increasing as we rally the Frontier team around our mission to Build Gigabit America.”


The company provided the following updates:

  • Frontier’s currently is able to deliver symmetrical 1 Gbps download and upload speeds;
  • The company plans to launch a symmetrical 2 Gbps offering in the first quarter of 2022 that will unlock next-generation digital experiences for customers;
  • Frontier plans to deploy fiber to reach 10 million locations by 2025; and
  • Frontier has set a new target of $250 million run rate savings by 2023 from simplifying its operations and improve the customer experience.

In addition, Frontier reported consolidated Q2 revenue of $1.62 billion, a 7.9% decline from consolidated revenue reported in the second quarter of 2020, due to declining consumer copper subscribers and wholesale revenue, and the impact of fresh start accounting. 

Frontier’s overall data and internet services revenue of $839 million decreased slightly in the second quarter of 2021 primarily due to declining copper subscribers. fiber broadband revenue was $268 million, a 13.6% increase over the second quarter of 2020, due to subscriber gains and higher ARPU. Consumer fiber net adds were approximately 12,000 in the quarter, the eighth consecutive quarter of positive consumer fiber net adds, resulting in broadband customer growth of 3.3% relative to the second quarter of 2020.

Second quarter 2021 operating income was $298 million. Net income was $4.58 billion due to approximately $4.2 billion of reorganization gains in the quarter, primarily related to the extinguishment of debt.

Capital expenditures increased to $385 million in the quarter from $225 million in the second quarter of 2020, as fiber expansion initiatives accelerated.

Vertical Systems: Gigabit services driving U.S. retail Carrier Ethernet

Gigabit services are the largest and fastest growing source of U.S. retail Carrier Ethernet revenue, according to Vertical Systems Group’s latest ENS (Emerging Networks Service). 

The Ethernet services delivered using 1 Gbps and higher speed ports now contribute more than half (54%) of U.S. Ethernet revenue, and comprise just over one quarter (26%) of ports installed at customer sites.

Solid revenue growth is projected through 2025 for gigabit port capacities, in contrast to revenue erosion for lower speed Ethernet connectivity. 

Vertical’s analysis includes detailed projections for six services across five speed segments. The speed segments are 10+ Gbps, 1 Gbps, 100 Mbps, 10 Mbps, and Sub-10 Mbps. Service segments covered include DIA (Dedicated Internet Access), Ethernet Access to IP/MPLS, EPL (Ethernet Private Lines), EVPL (Ethernet Virtual Private Lines), Metro LAN and WAN VPLS (Wide Area Network Virtual Private LAN Service).

Ethernet Research Highlights

  • Total U.S. Ethernet revenue dipped as a result of COVID-related disruptions and price compression, however the number of Ethernet ports installed at customer sites continued to expand.
  • 1 Gbps is the top speed segment based on Ethernet revenue through 2025.
  • 100 Mbps remains the largest Ethernet speed segment based on customer port installations.
  • EPL is the top Ethernet service segment based on revenue through 2022.
  • DIA has the highest projected CAGRs through 2025 for both ports and revenue. Demand for DIA is boosted by requirements for secure, dedicated connectivity to cloud services and data centers, as well as access links for SD-WAN underlays.
  • Bandwidth utilization for U.S. Ethernet customer ports is climbing at double digit rates. By 2025, gigabit speed services will contribute an estimated 97% of total Ethernet bandwidth.
  • Requirements for gigabit Ethernet services are spurring new fiber buildouts. All of the Ethernet Service Providers ranked on Vertical’s Mid-2021 U.S. Carrier Ethernet LEADERBOARD also hold a rank position for fiber provider leadership on the latest U.S. Fiber Lit Buildings LEADERBOARD.
  • Ethernet price compression continues across every service and speed combination as billed to customers (i.e., average ‘street price’ net of discounts).
  • Challenges to Ethernet market expansion include SD-WAN, wavelength services and dark fiber.

Nokia and MediaTek achieve 3.2 Gbps with FDD/TDD aggregation

Nokia and MediaTek achieved 3.2Gbps peak downlink throughput by aggregating 5G Standalone (5G SA) spectrum using 3 Components Carrier (3CC) aggregation, effectively combining 210MHz of FDD and TDD spectrum.

Nokia supplied its latest AirScale equipment including its AirScale 5G SA architecture powered by its ReefShark System-on-Chip (SoC) technology as well as its cloud-native 5G core. MediaTek provided its new M80 5G modem which combines mmWave and sub-6 GHz capabilities onto a  single chip as well as the user equipment testing platform.


Frequency division duplex (FDD) in 600MHz (n71) is a lower frequency band that provides a wide coverage area, improving cell edge performance. Time-division duplex (TDD) in 2600MHz (n41) has higher bandwidth and capacity. The combination of these spectrum bands supports a range of 5G deployment scenarios including indoor as well enhanced outdoor coverage. The high-band sub-6Ghz spectrum bands support high-capacity and extreme mobile broadband capabilities.

JS Pan, General Manager, Wireless Communication System, and Partnerships at MediaTek, said: “This test demonstrates the importance of carrier aggregation in enabling mobile operators around the world to deliver best-in-class speed and capacity to their subscribers. The combination of Nokia’s AirScale portfolio and our technology boosts the possibilities of spectrum assets and 5G networks. We look forward to continuing to partner with Nokia to advance the 5G ecosystem.”
