Ethernet Media Standards Ethernet, Fast Ethernet and Gigabit Ethernet, are identified by three-part names, which is also known as Media Standard. An example of Media Standard is 10BASE-T. The first part of the Media Standard specifies the transmission speed (10, in this case specifies 10 Mbps) The second part of the name "BASE" specifies that the Ethernet signal is a Basebandsignal. The final part of the Ethernet Media Standard specifies the kind of cable used. Here "T" specifies twisted-pair cable. The following table shows the common Ethernet Media Standards. Media Standard Cable Type Bandwidth Capacity Maximum Length 10Base2 Coax 10 Mbps 185m 10Base5 Coax 10 Mbps 500m 10BaseT UTP (CAT 3 or higher) 10 Mbps 100m 100BaseTX UTP (CAT 5 or higher) 100 Mbps 100m 10BaseFL Fibre Optic 10 Mbps 2Km 100BaseFX Fibre Optic 100 Mbps HD 400m/FD 2km 1000BaseT UTP (CAT 5e or higher) 1 Gbps (1000 Mbps) 100m 1000BaseSX Fibre Optic 1 Gbps (1000 Mbps) MMF 550m 1000BaseLX Fibre Optic 1 Gbps (1000 Mbps) MMF 500m/SMF 10km 1000BaseCX Fibre Optic 1 Gbps (1000 Mbps 100m 10GbaseSR Fibre Optic 10 Gbps 300m 10GbaseLR Fibre Optic 10 Gbps SMF 10km
