IEEE forms group on single-lane 25 Gb/s Ethernet standard

IEEE has formed the IEEE 802.3 25 Gb/s Ethernet Study Group to explore the market opportunities for a single-lane 25 Gb/s speed for server interconnects for Ethernet.

“The new study group expects to lay the groundwork for a new Media Access Control (MAC) rate that will enable cost-optimized single-lane solutions that will increase network deployment efficiency,” said Mark Nowell, chair of the IEEE 802.3 25 Gb/s Ethernet Study Group and senior director, Cisco Systems.

Companies building data centers are looking for IEEE 802.3 standards-based interoperable solutions that will enable a multi-vendor eco-system providing a cost optimized solution.

The reuse of serial lane 25 Gb/s signaling technology — developed to support 100 Gb/s Ethernet — enables cost optimized deployments in newly constructed data centers. This is especially true for the companies that will need server interconnects that support 10 Gb/s Ethernet and beyond.

“This study group will provide the opportunity to explore the possible development of a single-lane 25 Gb/s Ethernet standard supporting those application spaces needing cost-optimized performance beyond 10 Gb/s Ethernet for large scale deployments,” said David Law, chair of the IEEE 802.3 Ethernet Working Group and distinguished engineer with HP Networking.
