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.”

The specification is available at https://25gethernet.org/ll-fec-specification

Infinera carries 800G wavelength at 96 Gbaud over 950km

Infinera completed a live network trial of 800G single-wavelength transmission at 96 Gbaud over 950 kilometers (km) across a long-haul link in a major North American network operator’s production network.

The production network trial, which was conducted over a third-party optical line system carrying live multi-vendor traffic, leveraged Infinera’s Groove (GX) Series, equipped with its sixth-generation dual-800G Infinite Capacity Engine (ICE6) technology.  The trial demonstrated Infinera’s vertically integrated ICE6 optical engine, which features second-generation Nyquist subcarriers, 64QAM with per-subcarrier long-codeword probabilistic constellation shaping, and per-subcarrier dynamic bandwidth allocation. The operator's network used G.652 fiber.

Infinera said the achievement signals a major industry milestone in driving down the cost per bit of telecommunications networks.

“The success of this trial proves our ability to transmit 800G high-baud-rate signals across significant distances, which will be instrumental in driving down network costs,” said Parthi Kandappan, Chief Technology Officer at Infinera. “This marks another major accomplishment for Infinera’s Optical Innovation Center, adding to its long history of pioneering innovations in optical networking.”

Tuesday, March 03, 2020  800G, Corning, Infinera, Optical  

Infinera has demonstrated the ability to carry an 800 Gbps wavelength across 800km on Corning’s TXF optical fiber.

The achievement leveraged Infinera’s sixth-generation Infinite Capacity Engine (ICE6) technology in a Groove (GX) Series platform transmitting 800G using 64QAM with probabilistic constellation shaping (PCS). ICE6 combines Infinera’s sixth-generation photonic integrated circuit with its in-house-developed 7-nanometer dual-channel 800G per-wave FlexCoherent digital signal processor.

Corning’s state-of-the-art TXF fiber is an ITU-T G.654.E compliant, ultra-low-loss, silica-core fiber with large effective area.

The companies said the success of the 800G trial highlighted the advanced features of Infinera’s vertically integrated ICE6 technology, including Nyquist subcarriers, per-subcarrier long-codeword PCS, and per-subcarrier dynamic bandwidth allocation, along with superior fiber designed to help meet growing bandwidth demands for network operators from metro to subsea network applications.

QSFP-DD800 MSA releases initial 800G transceiver spec

The Quad Small Form Factor Pluggable Double Density 800 (QSFP-DD800) Multi Source Agreement (MSA) group has released a new hardware specification for the QSFP-DD800 transceiver form factor.

The new QSFP-DD800 1.0 specification is intended to be incremental to the existing QSFP-DD 5.0 specification. As signal integrity and thermal performance remain imperative, the transceiver pads have been optimized to improve signal integrity for 100 Gbps performance per lane without affecting backwards compatibility. The new specification additionally defines a novel 2x1 connector/cage, with cabled upper ports as an option to address signal loss issues associated with tradition PCBs. Looking ahead, QSFP-DD800 promoters will continue to work on new connector/cage variants, including 2x1 SMT versions that operate at 100 Gbps per lane.

The MSA group was formed to advance the development of high-speed, double-density QSFP modules which support 800 Gbps connectivity and includes the following promoters: Broadcom, Cisco, II-VI, Intel, Juniper Networks, Marvell, Molex and Samtec.

“In the short time our group has collaborated, we are thrilled to introduce this first specification for the next generation of the QSFP family of modules,” said Scott Sommers, co-chair of the QSFP-DD800 MSA. “As signal integrity and thermal management remain challenges for the optical communications industry, our MSA group is confident that its solutions will meet performance needs.”

“With their superior system integration and design flexibility, QSFP modules continue to be the cornerstone in building next generation networks and network equipment, especially as port speeds increase to 800G,” said Mark Nowell, co-chair of the QSFP-DD800 MSA. “Furthermore, their ability to increase switch and routing bandwidth density without sacrificing backwards compatibility with QSFP-DD, QSFP56 and QSFP28 modules provide network operators tremendous commercial and operational advantages.”
