Gigabit networking, or commonly called 10-Gigabit Ethernet (10GBASE-T), is a communications technology that offers Data speeds up to 10 billion bits per second.

10-Gigabit Ethernet is used to interconnect Local Area networks (LANs), wide area networks (WANs), and metropolitan area networks (MANs). 10-Gigabit Ethernet uses IEEE 802.3 Ethernet media access control (MAC) protocol. Like FAST Ethernet and Gigabit Ethernet, 10-Gigabit Ethernet uses full-duplex transmission, which makes possible a considerable distance range. With Multimode fiber, 10-Gigabit Ethernet will support distances up to 300 meters; using singlemode fiber, it will support distances up to 40 kilometers. Smaller Gigabit Ethernet networks may Feed into a 10-Gigabit Ethernet network.
