Cable Requirements

Ethernet Cable

A CAT 3~7 UTP (unshielded twisted pair) cable is typically used to connect the Ethernet device to the bridge. A 10Base-T

cable often consists of four pairs of wires, two of which are used for transmission. The connector at the end of the 10Base-T

cable is referred to as an RJ-45 connector and it consists of eight pins. The Ethernet standard uses pins 1, 2, 3 and 6 for

data transmission purposes. (
