GigE and 10 GigE Specifications
The original IEEE 802.3 specification for Ethernet described LAN communication at speeds of 10 Mbps. As Ethernet matured, the speed increased first to 100 Mbps and then to 1000 Mbps or 1 Gbps. Ethernet running at 1 Gbps is also called GigE. Several Ethernet standards define GigE, depending on the physical medium. The latest Ethernet LAN standard is 10 times faster, or 10 Gbps.
