Nokia debuts WaveFabric Elements: photonic chips, devices, subsystems

Nokia unveiled its WaveFabric Elements portfolio of photonic chips, devices and subsystems, including its fifth generation coherent digital signal processor family, the Photonic Service Engine V (PSE-V).
The company said its WaveFabric Elements address the demanding power, performance, and cost-per-bit requirements of 400G networking across data center, metro, core and subsea applications.

Nokia’s WaveFabric Elements portfolio combines digital signal processing (DSP) and optics technologies focused on emerging end-to-end 400G applications. The new, fifth generation coherent DSP family consists of multiple designs optimized for different optical networking applications, form factors, and platforms. These include:

  • PSE-Vs (super coherent), which can run up to 90 Gbaud and employ the second generation of Nokia Bell Labs-pioneered probabilistic constellation shaping (PCS). PSE-Vs are capable of transporting up to 800G, while providing 60% greater reach, 40% lower power per bit, and 15% greater spectral efficiency than previous DSP generations. 
  • PSE-Vc (compact), which enables programmable capacity from 100G to 400G with metro to long haul capability. Its extremely low power enables integration into a variety of pluggable transceiver modules.

The new DSPs are complemented by the CSTAR portfolio of coherent optical modules from its recent acquisition of Elenion Technologies. CSTAR leverages state-of-the-art silicon photonics and packaging technology, and addresses applications, including intra-data center, metro DCI and long-reach optical transport. In addition to pairing them with the new PSE-V DSPs within Nokia platforms, the company will sell them independently to industry partners for integration into pluggable transceiver modules available to the broader market.

The CSTAR family of optical engines is currently shipping to customers. PSE-V-based platforms and pluggables will be available beginning in Q4 2020.

Sam Bucci, Head of Optical Networks at Nokia, said: "Networks are truly at an inflection point, and 400G will be a catalyst for a significant transformation. With our WaveFabric Elements portfolio, Nokia is committed to supplying the 400G optical ecosystem with components, subsystems and design services, as well as continuing to build the highest performing optical transport solutions for the 400G era and beyond."

Whitepaper: 7 Principles of AT&T’s Network Transformation

AT&T published a nine-page whitepaper outlining seven tenets of its network transformation.

In a blog post, Scott Mair, President, AT&T Technology & Operations, says the company's network carried an average of 335 petabytes of data per day during Q4 2019. This jumped 20% because of the COVID-19 response. AT&T is on track to hit is its 75% SDN and automation goal this year, to deliver nationwide 5G this summer, and to expand its 400G deployment.

The whitepaper discusses the following “7 Principles of AT&T’s Network Transformation”:

  1. Network growth necessitates economies of scale that can only be achieved from interoperability and open disaggregation
  2. White Box hardware/software disaggregation using open dNOS, such as AT&T’s Vyatta NOS, is proliferating from the network edge to the core
  3. Network edge densification is critical for low latency, near-real time connections, highspeed requirements for 5G and low latency enterprise applications
  4. AT&T’s Mobility Core and IP Communication Core are pivoting to be cloud native
  5. ONAP and AT&T’s ECOMP SDN platform are evolving for diverse NFV instantiation orchestration models - APIs not GUIs
  6. Cloud-Based Data Warehouse, Machine Learning, Artificial Intelligence, and policy-driven SDN-control are a powerful combination 
  7. AT&T network security paradigm is rapidly changing from the customer premise, to the network edge, and at its core

Dell'Oro: Demand for 400G switch expected to grow this year

Ethernet Switch Data Center port shipments are forecast to surpass 60 million by 2024, with more than 50 percent of the port shipments will operate at 100 Gbps, 400 Gbps and 800 Gbps - according to a recent report from Dell'Oro Group.

“800 Gbps, 400 Gbps, as well as new waves of 100 Gbps will be enabled by faster SerDes technologies and higher speed optics,” said Sameh Boujelbene, Senior Director at Dell’Oro Group. “Optics will continue to play a vital role in the data center switch market. The availability of high volume, low-cost optics is crucial in driving any speed transition. Additionally, as network speed increases beyond 800 Gbps, pluggable optics will hit density and power issues. Hence it will become imminent for the industry to adopt alternative options such as Co-Packaged Optics (CPO). We expect such transition to bring major disruptions to the supply chain as it requires new business and serviceability models,” added Boujelbene.

Additional highlights from the Ethernet Switch – Data Center 5-Year Forecast Report:

  • Demand for 400 Gbps from the broader market is expected to ramp by end 2020 and in early 2021.
  • 400 Gbps and higher speeds are predicted to account for more than 25 percent of port shipments by 2024.

Inphi samples first 400ZR QSFP-DD transceiver

Inphi has begun sampling its COLORZ II 400ZR QSFP-DD pluggable coherent transceiver for cloud data center interconnects (DCIs) to major cloud operators and OEMs.

Inphi cites several industry firsts for its COLORZ II 400ZR QSFP-DD:

  • 400G single-chip, coherent Silicon Photonics Integrated Circuit (PIC) that includes all transmit and receive functions 
  • Innovative, low cost, passive alignment of fiber to the PIC that eliminates the complicated active alignment, using traditional optics
  • Low power, high performance, 7nm CMOS-based coherent DSP enabling 400ZR as well as extended reach 100/200/300/400G ZR+ modes
  • Integrated industry standard firmware management interface that enables full performance monitoring previously only available in DCI or transport systems directly from the optical module

 The 400ZR standard promises to lower the cost and power consumption of metro data center interconnect (DCI) by enabling switch and router companies to offer the same density for both coherent DWDM and client optics in the same chassis. This eliminates a layer of network connectivity that was previously required and supports high capacity DWDM connectivity directly from data center switches. 

Inphi said its COLORZ II represents a massive increase in switch rack capacity, while reducing the power consumption by as much as 80%. COLORZ II delivers up to 14.4T of capacity per rack unit (RU), compared to 2.4T or 3.6T per RU on competing solutions, representing a 4-6 x increase in throughput per chassis.

“Inphi continues to innovate as we provide an expanding suite of choices for cloud network operators and OEMs to gain the flexibility of high bandwidth DWDM connectivity in between data centers with the ability to rapidly scale their capacity,” said, Dr. Loi Nguyen, Sr VP, Optical Interconnect, Inphi. “By meeting the needs of cloud network companies that require extended link reaches, the 400ZR opens up new possibilities for DCIs to reduce total cost of ownership of cloud networks. As a fabless company we have proven our capability to quickly increase manufacturing and market share for our COLORZ 100G DWDM modules and are ready to meet our customers demand for COLORZ II.”

Inphi launches 7nm coherent DSP supporting 400G

Inphi has begun sampling its new Canopus coherent Digital Signal Processor (DSP) based on 7nm technology and supporting high-density QSFP-DD, OSFP and CFP2-DCO coherent pluggable modules for cloud and telecom applications.

Canopus leverages Inphi’s M200 coherent DSP techology enabling interoperability across generations of coherent solutions for 100G and 200G deployments to drive a seamless transition to 400G.


Canopus supports 400G ZR, which is being standardized in OIF facilitating multi-vendor interoperability up to 120km span. Inphi contributed an innovative FEC technology called CFEC, adopted by multiple standards bodies including OIF, IEEE and ITU for the 400G ZR standard. Canopus extends performance beyond ZR to ZR+ extending 400G reach and spans lower data rates to thousands of kilometers on metro and long haul networks.

Canopus also implements probabilistic shaping, a technique that maximizes data rate at longer fiber distances and delivers lower deployment cost per bit. This is the first time that coherent pluggables are powered with probabilistic shaping technology.


The implementation in 7nm silicon geometry delivers over 75% reduction in DSP power dissipation and size as compared to the current generation of coherent DSPs.

“The Canopus coherent DSP is ushering a new industry wide ecosystem, pluggability, and era of interoperability.

Juniper extends 400GbE over 2,000 km

Juniper Networks delivered 400Gbps Ethernet live traffic over 1,300 miles (2.092 km) in a trial conducted in conjunction with SCinet, the Supercomputing 2019 Conference's high-capacity network.

SCinet used Juniper’s PTX10003 Packet Transport Router to deliver traffic between Denver and Chicago. The 400GbE link was part of the 4.22 Terabits of connectivity SCinet provided to the conference. It was made available to researchers working on projects in disciplines, such as High Energy Physics, Radio Astronomy and Human Genome research. Over the coming years, many Research & Education networks will be upgrading their backbones to 400GbE, positioning them to meet the bandwidth demands of Big Science.

Juniper also supplied SC19 with additional networking infrastructure to build SCinet and support the conference, including MX2019 and MX960 routers, QFX switches and SRX4600 firewalls. All infrastructure ran the Junos operating system with the one Junos experience optimized for the modularity, openness and programmability required of the new cloud era in networking.

“This field trial represents a significant milestone in realizing the promise of 400GbE’s high-capacity, next-gen networks. Juniper Networks has a long history of leading the industry in fast and simplified networking. By delivering cutting-edge innovations in 400GbE networks, we are laying the foundation for the fastest and most advanced networks in the world,” stated Andy Athreya, Chief Development Officer at Juniper Networks.

Credo Joins Open Compute Project (OCP) to Accelerate 400G

Credo, which develops Serializer-Deserializer (SerDes) technology for 100G, 400G, and 800G, has joined the Open Compute Project (OCP).

“As disaggregated chassis begin to displace tradition big-iron switching and routing chassis, low power, highly flexible and routable 400G interconnect becomes a core component of the architecture,” said Don Barnetson, Sr. Director of Product at Credo. “OCP provides a platform to standardize and proliferate 400G disaggregated chassis configurations at hyperscalers around the world.”

Credo is also a member of the HiWire Consortium, announced in September 2019 with 25 other founding members, nearly half of whom are also amongst the OCP ranks. Working in harmony with other standards bodies, the HiWire Consortium is dedicated to the standardization and certification of a new interconnect cable category, Active Electrical Cables (AECs), enabling its broad support and wide industry adoption.

Credo began the development of AECs two years ago to address the obstacles that were slowing the transition to 400G, specifically the performance and physical limitations of copper (DACs) and the power, cost, and availability hurdles of active optical cables (AOCs). AECs integrate retimer and PAM4 to NRZ speedshifting functions with gearbox in-cable making them a lower power, affordable plug and play interconnect for 100G and 400G systems.

Credo says the power, performance, and price of AECs are empowering system architects to rethink the design of next-generation data center configurations, deploy 400G disaggregated chassis and provide a clear path to 800G in the future.

AT&T activates first 400G circuit on Dallas/Atlanta route

AT&T activated its first 400-gigabit optical connection on a Dallas-to-Atlanta fiber route -- an industry first for a 400G long haul commercial link, according to the company.

The 400G trunk is now carrying live Internet traffic for customers. This connection – between Dallas and Atlanta – is believed to be a first in the industry.

The 400G Dallas/Atlanta facility was deployed on an SDN-enabled Ultra Long Haul (ULH) system from Ciena. The 400G circuit was routed and configured completely through software using Ciena’s Manage, Control and Plan (MCP) domain controller. The 400G transport was terminated in the Dallas and Atlanta offices by a white box router from UfiSpace that is compliant with the Broadcom Jericho2 Distributed Disaggregated Chassis (DDC) design that AT&T recently submitted to the Open Compute Project (OCP). 400G pluggable transceivers from InnoLight were installed in the white box router and Ciena transponder to create the cross-office connectivity between the packet and optical technologies. Ciena’s MCP controller is integrated into AT&T’s ONAP management and control framework using an Application Programming Interface (API) specified by the Open ROADM Multi-Source Agreement (MSA).

The optical transport system consists of a new 400G transponder based on Ciena’s WaveLogic Ai coherent optical technology. The Ciena Reconfigurable Optical Add/Drop Multiplexors (ROADMs) have been upgraded with new software to support a sophisticated feature known as flex grid. This allows us, through software control, to optimize the allocation of spectrum on the long-haul fiber based on the required speed and reach of each wavelength. The Broadcom Jericho2 white box was supplied by UfiSpace and provides 10 x 400G interfaces on a 2RU “pizza box”. The white box uses the Broadcom Jericho2 packet processing chip, a state-of-the-art chip designed to meet the demanding needs of a service provider.

“The move from a 100G interface to 400G is a milestone for the communications industry, because it means we can continue to stay ahead of the tsunami of data demand we’ve seen over the last decade-plus,” said Andre Fuetsch, executive vice president and chief technology officer, AT&T. “This accomplishment also speaks to the tremendously collaborative ecosystem we’ve helped foster with key innovators in optical technology, white box hardware, and software-defined networking. Ciena, UfiSpace, Broadcom, and InnoLight have brought great ideas and technologies to bear to make 400G a reality.”

“We are very proud to collaborate with AT&T on the design of the white boxes based on Broadcom’s Jericho2,” said Vincent Ho, general manager of UfiSpace. “In spite of the complexity and difficulty with the design from an electrical, mechanical, and thermal perspective, we’ve used our breadth of understanding in networking to overcome the challenges rolling out the first 400G carrier-scale white box solution. UfiSpace is very excited to be amidst the first to participate and contribute to this new paradigm. We are thankful to AT&T for their leadership in building a robust and open white box ecosystem.”
