IEEE 802.3by 25 Gigabit Ethernet standard published

The IEEE and the IEEE Standards Association (IEEE-SA) have published "IEEE 802.3by Standard for Media Access Control Parameters, Physical Layers and Management Parameters for 25 Gb/s Operation." The new 25 Gigabit Ethernet specs aim to address server connectivity demands that have crept beyond 10 Gbps.

The new standard provides specifications for 25 Gigabit Ethernet transmission over electrical backplanes, copper twin-axial cables of 3 to 5 m and multimode fiber up to 100 m. The IEEE recently launched an effort to create specifications for 25 Gigabit Ethernet over single-mode fiber (see "IEEE approves standards initiatives for 25 Gigabit Ethernet, 50, Gigabit Ethernet, 200 Gigabit Ethernet").

"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."
