IEEE Publishes 802.3by™ 25 Gb/s Ethernet Standard For Server Interconnectivity
Standard amendment defines Ethernet Media Access Control (MAC) parameters, physical layer specifications, and management parameters.
IEEE and the IEEE Standards Association (IEEE-SA) have announced the publishing and availability of IEEE 802.3by™ Standard for Media Access Control Parameters, Physical Layers and Management Parameters for 25 Gb/s Operation. The new amendment to IEEE Standard 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.”
IEEE 802.3by supports efficient Ethernet operation and 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.
IEEE 802.3by is available for purchase at the IEEE Standards Store.
Deployment of technology defined by IEEE 802® standards is already globally pervasive, driven by the ever-growing needs of data networks around the world. New application areas are constantly being considered that might leverage IEEE 802 standards in their networks from wireless, through twisted-pair cabling, to fiber-optic cabling solutions. To better address the needs of all of these areas, IEEE 802 standards are constantly evolving and expanding. The success of IEEE 802 standards — from their inception through today — has been their fair, open and transparent development process.
