100BASE-TX

100BASE-TX is the predominant form of Fast Ethernet, providing 100MBps Ethernet.

100baseTX runs over two pairs of wires in category-5 cable. Like 10BASE-T, the proper pairs are the orange and green pairs (canonical second and third pairs) in the TIA-568B wiring standard.

In TIA-568B, wires are in the order 1, 2, 3, 6, 5, 4, 7, 8 on the modular jack on each end. The colour-order would be orange/white, orange, green/white, blue, blue/white, green, brown/white, brown.

Each segment can have a maxium distance of 100 metres. Capable of 100Mbps throughput. See IEEE 802.3 for more details.
