IEEE 802.3ae
IEEE 802.3ae (also 802.3ae-2002 ) was the first Ethernet standard for 10 Gbit / s connections. It dates from 2002 and defines fiber optic connections to 10GBASE-SR, 10GBASE-LR, 10GBASE-ER, 10GBASE-SW, 10GBASE-LW and 10GBASE-EW ( 10 Gigabit Ethernet ), which from the series IEEE 802 originate .
Depending on the physical interface PHY of the transport medium, the standard enables transmissions with max. 10 Gbit / s per multimode - fiberglass m over lengths of 25 (10GBASE-SR) up to max. 300 m (10GBASE-LX4) and via singlemode fibers of up to 40 km (10GBASE-ER).

development
The IEEE 802.3ae working group was set up in November 1999 and published the IEEE 802.3ae standard for fiber optic connections in June 2002. The IEEE 802.3ak working group , which dealt with the standardization of 10 Gbit / s connections over copper cables, became more comparable Tasks 2005 merged with her.
