Definition[edit | edit source]
100BASE-TX is the predominant form of fast Ethernet, and runs over two wire-pairs inside a category 5 or above cable (a typical category 5 cable contains 4 pairs and can therefore support two 100BASE-TX links).
Overview[edit | edit source]
Each network segment can have a maximum distance of 100 meters (328 ft). In its typical configuration, 100BASE-TX uses one pair of twisted wires in each direction, providing 100 Mbit/s of throughput in each direction (full-duplex).
