Gigabit Ethernet is a networking standard based on Ethernet-standard packets of information sent over optical fibres or ordinary twisted-pair cabling at up to 1000 megabits per second.
Also known as 802.3z and 802.3ab, Gigabit Ethernet uses the same signalling speed as 100 megabit Ethernet but uses all four pairs of wires in the cable and a more efficient modulation scheme to get ten times the performance. To use Gigabit Ethernet, you'll need new network interface cards and hubs, switches and/or routers. The rest of the Ethernet standard is as before.
Currently being used as the backbone in many enterprise network.
