IEEE Std 802.3™-2022 Standard for Ethernet

by

Ethernet is the world’s most popular computer networking protocol used in local area network (LAN), metropolitan area network (MAN), and wide area network (WAN) communication. The IEEE 802.3 Ethernet Working Group develops Standards for wired networks where physical connections are made between nodes and/or infrastructure devices (hubs, switches, routers) with various types of optical fiber and copper cabling. Optical Ethernet applications supported by TIA building IT infrastructure Standards include:

Plastic optical fiber or POF, commonly used in automotive Ethernet applications, and copper media types supporting Ethernet operation (i.e., balanced twisted‑pair cabling, twinaxial cabling, and electrical backplanes) are outside the purview of the TIA FOTC.

The first IEEE 802.3 Standard was published in 1983. New Ethernet projects publish as amendments to the base document and are incorporated into the parent document when a new revision publishes. Since 1983, there have been 9 revisions to IEEE Std 802.3. The latest version is IEEE Std 802.3™‑2022.
