IEEE Publishes 802.3by 25 Gb/s Ethernet Standard for Server Interconnectivity

IEEE officially released its 802.3by Standard for Media Access Control Parameters, Physical Layers and Management Parameters for 25 Gb/s Operation.

The standard defines single-lane 25 Gb/s PHYs for operation over electrical backplanes, copper twin axial cables with lengths up to 3-5 meters and multimode fiber with lengths up to 100m.
IEE said this new amendment to 802.3 represents the first available industry standard developed specifically to address the growing need for increased Ethernet speeds for server interconnects exceeding 10 Gb/s, and one that offers cost-saving advantages over current higher speed Ethernet offerings.

“We have been fortunate to pool the resources of many individuals who’ve demonstrated considerable dedication and commitment to work collaboratively to advance a much sought after standard for 25 Gb/s Ethernet,” said Mark Nowell, chair, IEEE P802.3by 25 Gb/s Ethernet Task Force. “The work of the IEEE P802.3by 25 Gb/s Ethernet Task Force epitomizes how standards development is a key factor in ensuring best practices, and how best to meet the rapid demands of industry as technological advancements are pursued in the respective areas where Ethernet continues to play a growing role.”
