High Quality Content by WIKIPEDIA articles! 100 Gigabit Ethernet (or 100GbE) and 40 Gigabit Ethernet (or 40GbE) are high-speed computer network standards developed by the Institute of Electrical and Electronics Engineers (IEEE). They support sending Ethernet frames at 40 and 100 gigabits per second over multiple 10 Gbit/s or 25 Gbit/s lanes. Previously, the fastest published Ethernet standard was 10 Gigabit Ethernet. They were first studied in November 2007, proposed as IEEE 802.3ba in 2008, and ratified in June 2010. Another variant, 802.3bg, was added in March 2011.
