10 Gigabit Ethernet

An Ethernet standard that transmits at 10 gigabits per second (10 Gbps). Introduced in 2002 and abbreviated "10 GbE," "10GE" or "10G Ethernet," it extended Gigabit Ethernet by 10-fold for high-speed storage networks (SANs), enterprise backbones, as well as wide area and metropolitan area networks. See Gigabit Ethernet, LAN, SAN, WAN and MAN.

Full Duplex and No Collisions
10G Ethernet works only in full-duplex mode and does not support CSMA/CD, the common Ethernet collision method used to gain access to the physical medium. A "WAN interface sublayer" (WIS) makes 10G Ethernet compatible with the SONET transport at 10 Gbps (OC-192). See SONET.

Fiber or Copper
The 10GBASE-LX4 version (see below) carries four wavelengths of light on one pair of fibers. In 2004, 10G Ethernet over copper wire was introduced. Using four twinaxial cables, the copper version was designed for short distances between switches and storage devices in the datacenter. See 25 Gigabit Ethernet, Ethernet and FCoE.
