The document describes the various Ethernet standards developed by IEEE 802.3 over time, starting from 1973 with experimental Ethernet up to the most recent standards from 2012. Key standards included 10 Mbit/s Ethernet in 1983, 100 Mbit/s Fast Ethernet in 1995, 1 Gbit/s Gigabit Ethernet in 1998, 10 Gbit/s Ethernet in 2003, and 40/100 Gbit/s Ethernet standards in 2010. The standards define various physical layer specifications for Ethernet over different cable types including coaxial cable, twisted pair, and fiber optic cable.
