Three standard amendments to IEEE 802.3 have been released:
- IEEE 802.3cb-2018—IEEE Standard for Ethernet—Amendment 1: Physical Layer Specifications and Management Parameters for 2.5 Gb/s and 5 Gb/s Operation over Backplane.
- IEEE 802.3bt-2018—IEEE Standard for Ethernet Amendment 2: Physical Layer and Management Parameters for Power over Ethernet over 4 pairs.
- IEEE 802.3cd-2018—IEEE Standard for Ethernet—Amendment 3: Media Access Control Parameters for 50 Gb/s and Physical Layers and Management Parameters for 50 Gb/s, 100 Gb/s, and 200 Gb/s Operation.

“The foresight, ingenuity and productivity of the thousands of volunteers developing the IEEE 802 family of standards since 1980 is truly remarkable, as evidenced by the worldwide impact their constantly evolving standards have had in response to ever-changing markets,” said Paul Nikolich, chair, IEEE 802 LAN/MAN Standards Committee.
