An Ethernet standard that transmits at 10 Mbps over twisted wire pairs (telephone wire). 10Base-T is a shared media LAN when used with a hub (all nodes share the 10 Mbps) and 10 Mbps between each pair of nodes when used with a switch. There are rarely new 10Base-T products. Most Ethernet adapters, hubs and switches are 10/100 devices, which support both 10Base-T and 100Base-T, which is 10 times as fast. (see 10/100 adapter).A Star ConfigurationIn the 1980s, 10Base-T began to be widely deployed. Using inexpensive and flexible twisted pair "telephone wires," 10Base-T Ethernet ("T" means twisted) was easier to install than previous "thick" and "thin" Ethernets that used coaxial cable. See 10Base5, 10Base2, 10Base-F, Ethernet and Ethernet switch.
The IEEE standard (1990), and for Cat 3, Cat 4, or Cat 5 unshielded twisted pair (UTP) in support of Ethernet transmission. 10Base-T translates to 10 Mbps (theoretical transmission rate), Baseband (one transmission at a time over a single, shared channel) transmission, and over Twisted pair media.The maximum segment length between the 10Base-T hub and the attached device (e.g., workstation or printer) is specified at 100 meters or less, although good Cat 5 cable will perform well over somewhat longer distances.The 10Base-T hub is a wire hub that serves as a multiport repeater, as well as a central point of interconnection.
