IEEE releases standard for 200G, 400G Ethernet

Tuesday 13 March 2018 | 14:25 CET | News

The IEEE has announced the release of new standards for the next generation of Ethernet services. The IEEE 802.3bs-2017 standard amendment for MAC Parameters, Physical Layers and Management Parameters will support 200 Gbps and 400 Gbps operations, in order to address the growing demand for bandwidth in a variety of applications. 

"The publication of IEEE 802.3bs represents a nearly five-year endeavour to ensure Ethernet’s continuing support of the accelerating curve for higher bandwidth that can support ongoing robust industry growth and expansion," said John D’Ambrosia, chair of the IEEE 802.3bs group and senior principal engineer at Futurewei, a subsidiary of Huawei.

Separately, the Ethernet Alliance announced at OFC in San Diego its new roadmap for the industry. The roadmap traces Ethernet’s path from 10 Mbps through present-day speeds of 1G to 400G Ethernet, and looks ahead to future speeds achieving up to 1.6 Tbps and beyond. The map provides guidance into key underlying technologies, current and future interfaces, and the numerous application spaces for Ethernet.

The Optical Internetworking Forum (OIF) and the Ethernet Alliance are holding an interoperating 400 Gbps Ethernet network demonstration at OFC. The joint demonstration will feature 400 Gbps of Flex Ethernet traffic sent over four bonded 100 GbE interfaces streaming over the Ethernet Alliance 400 GbE network and interconnecting the OIF and Ethernet Alliance booths on the exhibit floor. The demonstration is designed to showcase the IEEE 802.3bs 400 Gbps standard and the OIF’s FlexE 1.1 Implementation Agreement.
