NeoPhotonics samples 400ZR OSFP coherent transceiver

NeoPhotonics began sampling its new 400ZR ClearLight OSFP transceiver to a leading cloud -related customer.

The new transceiver utilizes NeoPhotonics Silicon Photonics Coherent Optical Subassembly (COSA) and low power consumption, ultra-narrow linewidth Nano-ITLA tunable laser, combined with the latest generation of 7 nm DSP, to provide full 400ZR transmission in a standard data center OSFP form factor.

NeoPhotonics said its new 400ZR ClearLight OSFP transceiver can be plugged directly into switches and router, simplifying data center interconnect (DCI) networks by eliminating a layer of network equipment and a set of short reach client-side transceivers. The new OSFP module is capable of tuning to 75 GHz or 100GHz spaced wavelength channels, as specified in the OIF agreement, and operates in 400ZR mode for Cloud DCI applications.  For longer metro reaches, the module  is designed to support 400ZR+ modes.

This ClearLight OSFP module can also be optionally provisioned to tune over the entire “Super C-Band”, or up to 6.4 Terahertz, increasing the capacity of an optical fiber by up to 50% over standard implementations.  NeoPhotonics provides arrayed waveguide gratings for multiplexing and de-multiplexing with 75GHz and 100GHz wavelength channel spacings, supporting 85 and 64 channels respectively, with filter responses optimized for high baud rate coherent signals.

"This new OSFP module joins our ClearLightTM DCO transceiver line and takes full advantage of our highly integrated and low power consumption Nano-Tunable Laser and Silicon Photonics COSA to enable a full metro coherent transceiver in the form factor and electrical interface designed for short reach interconnections inside the data center," said Tim Jenks, Chairman and CEO of NeoPhotonics. "We are now sampling these OSFP transceivers so that customers can evaluate the simplicity, cost and operating savings that can be realized by plugging coherent optics directly into switches and routers, and we are applying this same technology to additional form factors such as QSFP-DD", concluded Mr. Jenks.

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 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. Canopus increases density while slashing both power dissipation and the cost per bit to unprecedented levels,” said Nariman Yousefi, SVP, Coherent DSP, Inphi. “The sampling of the Canopus DSP transforms coherent pluggable optics to high-performance 100/200/300/400G, a true revolutionary step and the inflection point in the industry.”


Inphi is facilitating an ecosystem of partners offering QSFP-DD, OSFP and CFP2-DCO modules, fueled with coherent advancements enabled by Canopus power and performance scalability. This will make Canopus truly interoperable ecosystem for data center interconnect, metro and long haul applications across multiple established module vendors in the industry, will drive supply diversity and accelerate time to deployment for OEMs and operators. Canopus ecosystem partners are equipped to deploy interoperable solutions across wide array of optical network links with ZR and ZR+.

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.”

Dell'Oro: 100 Gbps port shipments to peak in 2020

400 Gbps shipments are forecast to surpass 15 M switch ports by 2023, according to a recently published report by Dell’Oro Group. 100 Gbps port shipments are expected to peak in 2020, but still comprise more than 30 percent of data center switch ports during the next five years.

“The first wave of 400 Gbps switch systems based on 12.8 Tbps chips were introduced in the market in the second half of 2018,”said Sameh Boujelbene, Senior Director at Dell’Oro Group. “However, we do not expect material adoption of 400 Gbps until 2020 due to the lack of high volume, low cost 400 Gbps optics. The only Cloud Service Provider that started deploying 400 Gbps was Google, opting for 2×200 Gbps optics with an earlier time-to-market. Meanwhile, we expect other Cloud Service Providers, for instance Amazon, Facebook and Microsoft, to keep deploying 100 Gbps, and to probably use higher density 100 Gbps switch systems based on the 12.8 Tbps chips to lower costs,” added Boujelbene.

The Ethernet Switch – Data Center 5-Year Forecast Report provides more details about the timing of 100/200/400/800 Gbps and how the use cases may vary depending on the SerDes lane and market segment driving the speed.

DE-CIX offers 400-GE access to its Frankfurt Exchange

DE-CIX has begun offering 400-GE access technology to its flagship Internet Exchange in Frankfurt, Germany, which handles the highest peak exchange traffic in the world.

DE-CIX first introduced 100-GE access in 2013.

The expansion is being realized on the DE-CIX Apollon platform, which uses Nokia routers as one core component. The 400-GE Nokia line cards are now available in DE-CIX Frankfurt.

DE-CIX said it will make 400-GE available at further DE-CIX locations over time.

“With the introduction of the 400-GE access technology, we once again underscore our claim to be a technology leader,” says Dr. Thomas King, Chief Technology Officer at DE-CIX. “We offer our customers newest generation hardware and a modern, scalable infrastructure, which will also be able to meet all requirements in the future. At the same time, we support the growth of our customers at our worldwide locations with the new technology. Because the more data traffic they can exchange over us, the more the investment in our services will pay off.”

“We have happily served DE-CIX for over six years with our cutting-edge equipment,” says Ken Kutzler, Vice President of Nokia’s IP Routing Hardware business. “Our routing R&D is heavily driven by the fast-growing, high-quality throughput demands of customers like DE-CIX.  Nokia is proud to be their partner and to help enable its first 400GE peering ports. Powered by the Nokia FP4 Chipset, DE-CIX can continue to expect deterministic loss-less performance, smooth operations and seamless upgrades as we move together into the future.”

DustPhotonics ships 400Gbps QSFP-DD SR8

DustPhotonics announced sampling availability and pre-production ramp of 400G QSFP-DD SR8 optical transceiver for short reach, high-density applications over multi-mode optical fiber. The 400Gbps module incorporates DustPhotonics' AuraDP optical engine with unique fiber integration and manufacturing technology .

Dust Photonics notes that 400G QSFP-DD SR8 transceivers support both 400G switch to switch and breakout options for high-radix configurations.

DustPhotonics claims its AuraDP light engine enables reduced power consumption, higher reliability, and superior module performance. The optical packaging design results in improved sensitivity and efficient coupling. The QSFP-DD optical transceiver is designed for use with cost effective multimode fiber and supports reaches of up to 100 meters using OM4 fiber. The SR8 module features; 8 parallel 50Gbps PAM4 optical channels, supports the latest CMIS Management Interface, and is compliant to the latest QSFP-DD MSA and IEEE 802.3bs 400GBASE SR8 standards.

The 400G QSFP-DD module is part of the DustPhotonic's family of 400G multimode transceiver and AOC product line. The 400G QSFP-DD SR8 has an expected production release date in the second half of 2019. DustPhotonics is currently sampling and accepting orders for evaluation of 400G QSFP-DD SR8 transceivers.

"QSFP-DD SR8 is the most versatile 400G module for the large enterprise and hyperscale cloud data center markets supporting fanout to 200G and 50G," says Ben Rubovitch, CEO and co-founder of DustPhotonics. "With the majority of fiber lengths in hyperscale data centers being less than 100 meters, multimode is the economic choice supporting high-radix interconnection networks. This offers significantly better cost/performance solutions needed for broad market adoption of 400Gbps data rates."
