DESCRIPTION

IEEE 802.3by-2016

This amendment defines Ethernet Media Access Control (MAC) parameters, physical layer specifications, and management parameters for the transfer of Ethernet format frames at 25 Gb/s for server to switch interconnections.



Amendment Standard - Superseded. This amendment to IEEE Std 802.3-2015 adds Physical Layer (PHY) specifications and management parameters for 25 Gb/s operation over twinaxial copper cabling (25GBASE-CR and 25GBASE-CR-S), electrical backplanes (25GBASE-KR and 25GBASE-KR-S), and multimode fiber (25GBASE-SR). This amendment also specifies a 25 Gigabit Attachment Unit Interface (25GAUI) and optional Energy Efficient Ethernet (EEE).
