IEEE Announces Amended IEEE 802.3bj Standard

Data Center | In Compliance Magazine

IEEE has released an amendment to the IEEE 802.3bj standard. IEEE 802.3bj applies to “Standard for Ethernet Amendment 2: Physical Layer Specifications and Management Parameters for 100 Gb/s Operation Over Backplanes and Copper Cables.” The updated standard is available for purchase on the IEEE website.


“IEEE 802.3 had previously defined 40 Gb/s and 100 Gb/s Ethernet to help alleviate bandwidth choke points in the network. Now IEEE 802.3bj adds 100 Gb/s operation over electrical backplanes and lower-cost, lighter-weight copper cables, as well as optional Energy Efficient Ethernet (EEE) for 40 Gb/s and 100 Gb/s links. These are critical enhancements to the standard that are intended to both optimize and expand Ethernet’s options for physical connectivity.”
