NeoPhotonics ships first coherent components for 800G and up

NeoPhotonics announced the first pilot shipments of Class 60 versions of its Coherent Driver-Modulator (CDM) and Intradyne Coherent Receiver (Micro-ICR) designed for the next generation of 96 GBaud and above systems supporting 800G rates.

NeoPhotonics said higher symbol rates increase data capacity while maintaining superior optical signal-to-noise ratio (OSNR) and reach performance, thereby enabling the highest speed-over-distance use. These new components are available in compact form factor packages suitable for use in pluggable modules and compact daughter cards. 

NeoPhotonics' Class 60 Coherent components extend the highest speed-over-distance performance of its existing Class 40 products by increasing the 3 dB bandwidth from 40 GHz to 60 GHz. These NeoPhotonics components work together to enable single wavelength data transmission near one Terabit per second over datacenter interconnect (DCI) distances, as well as 400~500Gbs transmission over long haul distances.

NeoPhotonics Class 60, polarization-multiplexed, coherent driver modulator (CDM) features a co-packaged InP modulator with four linear, high bandwidth, differential drivers, and is designed for low modulation voltage, or “V-Pi”, low insertion loss, and a high extinction ratio. The compact package is compliant with the form factor of the OIF Implementation Agreement #OIF-HB-CDM-01.0. NeoPhotonics Class 60 High Bandwidth Micro-Intradyne Coherent Receiver (Micro-ICR) is designed for 96 GBaud symbol rates, essentially tripling the rate of standard 100G ICRs. The compact package is compliant with the OIF Implementation Agreement OIF-DPC-MRX-02.0.

These components work with NeoPhotonics’ “Nano” Ultra-Narrow Linewidth external cavity tunable laser, which cuts the size approximately in half compared to current Micro-ITLAs, while featuring industry-leading linewidth, low phase noise, and low electrical power consumption.

“We are pleased to be shipping initial quantities of our Class 60 coherent modulators and receivers, which along with our Ultra-Narrow Linewidth external cavity 'Nano' tunable laser, provide a complete suite of components enabling customers to efficiently implement 800Gbps per wavelength coherent communications systems,” said Tim Jenks, Chairman and CEO of NeoPhotonics. “We are further extending the bandwidth of our Indium Phosphide coherent integration platform by developing Class 80 components for 130 Gbaud operation as we continue to serve the highest speed-over-distance applications,” concluded Mr. Jenks.

Windstream carries 800G wavelength over 730km using Infinera

Windstream successfully achieved 800 Gbps single-wavelength transmission over 730 kilometers across its long-haul network between San Diego and Phoenix. The test used Infinera’s fifth-generation coherent optical technology, ICE6 (Infinite Capacity Engine), equipped in a Groove (GX) Series platform over industry-standard G.652-compliant SMF-28 fiber. By looping back the signal, the test also achieved a 700G transmission over 1,460 km.

The record performance was enabled by advances in Nyquist subcarriers, a pioneering innovation developed by Infinera’s Optical Innovation Center (OIC). Nyquist subcarrier-based solutions map the traffic into tightly packed, lower-baud-rate digital subcarriers within a single optical carrier. Infinera says subcarriers also amplify the benefits of its other OIC innovation, such as 64QAM long-codeword probabilistic constellation shaping and dynamic bandwidth allocation.

The companies said the trial demonstrates that ultra-high-speed optical transmissions, such as 700G and 800G, can be deployed in real-world network applications over significant distances. This will enable emerging 400 Gigabit Ethernet (400 GbE) services to be supported over longer distances within the Windstream national network. High-performance, high-speed transmission will also enable network operators like Windstream to realize increased efficiency in cost per bit and power per bit, as well as increased capacity per fiber by as much as 70 percent compared to third-generation (400G) coherent technology and by as much as 35 percent compared to fourth-generation (600G) coherent technology.

“Windstream remains committed to staying at the forefront of technological innovation and the superior performance of ICE6 brings real-world value to our network and enables us to meet the explosive growth in bandwidth demands of our customers,” said Buddy Bayer, chief network officer at Windstream. “The flexibility of ICE6 coupled with the easily deployable compact modular form factor of the GX Series will enable Windstream to quickly and easily introduce this new technology across our entire network from edge to core.”

“Infinera is delighted to set this new industry benchmark and partner with Windstream, a network operator that continually pushes the boundaries of optical networking,” said Parthiban Kandappan, chief technology officer at Infinera. “As proven by the superior performance of this network trial, we believe our unique expertise with Nyquist subcarriers coupled with the groundbreaking innovations introduced by ICE6 will represent the standard for high-speed optical engines going forward.”

Ethernet Technology Consortium focuses on 800G

The 25 Gigabit Ethernet Consortium, originally established to develop 25, 50 and 100 Gbps Ethernet specifications, has changed its name to the Ethernet Technology Consortium in order to reflect a new focus on higher-speed Ethernet technologies, the 800GBASE-R specification for 800 Gigabit Ethernet (GbE).

The 800 GbE specification introduces a new media access control (MAC) and Physical Coding Sublayer (PCS). It essentially re-purposes two sets of the existing 400GbE logic from the IEEE 802.3bs standard with a few modifications in order to distribute the data across eight 106 Gb/s physical lanes. As the PCS is reused, the standard RS(544, 514) forward error correction is retained, for simple compatibility with existing physical layer specifications.

The Ethernet Technology Consortium said its goal is to enhance the Ethernet specification to operate at new speeds by utilizing specifications that are developed or in development. This allows the organization to work alongside other industry groups and standards bodies to adapt Ethernet at a pace that aligns with the rapidly evolving needs of the industry. The ETC has more than 45 members with top-level promoter members that include Arista, Broadcom, Cisco, Dell, Google, Mellanox and Microsoft.

“Ethernet is evolving very quickly and as a group, we felt that having 25G in the name was too constraining for the scope of the consortium,” said Brad Booth, chair of the Ethernet Technology Consortium. “We wanted to open that up so that the industry could have an organization that could enhance Ethernet specifications for new and developing markets.”

“The intent with this work was to repurpose the standard 400GbE logic as much as possible to create an 800 GbE MAC and PCS specification with minimal overhead cost to users implementing multi-rate Ethernet ports,” said Rob Stone, technical working group chair of the Ethernet Technology Consortium. “The 800 GbE specification is an exciting first announcement under the consortium’s new name, reflecting the true capability of the organization. We are proud of the hard work of our member companies in completing this specification.”

Low latency spec for 50GbE tweaks forward error correction

Tuesday, February 19, 2019  25G, 50G, Specs, Standards  

The 25 Gigabit Ethernet Consortium has completed a low-latency forward error correction (FEC) specification for 50 Gbps, 100 Gbps and 200 Gbps Ethernet networks.

The new spec cuts FEC latency approximately in half by using a shortened codeword FEC variant – RS (272, 257+1, 7, 10) that replaces the IEEE 802.3cd and 802.3bs standard FEC.  The shortened codeword contains 272 x 10-bit symbols rather than the 544 x 10-bit symbols originally specified. Nothing else changes in the symbol distribution process from the output of the encoder to the FEC lanes in the new FEC, but that process is implemented more quickly due to the shortened codeword.

This will have a significant impact on overall physical layer latency, in particular for hyperscale datacenter networks comprised of a large number of nodes, with multiple hops between servers.

“Five years ago, only HPC developers cared about low latency, but today has latency sensitivity has come to many more mainstream applications,” said Rob Stone, technical working group chair of the 25G Ethernet Consortium. “With this new specification, the consortium is improving the single largest source of packet processing latency, which improves the performance that high-speed Ethernet brings to these applications.”
