A balanced cable where a pair of cables are twisted and the signal divides between them

Twisted-pair cable consists of copper wires surrounded by an insulator. Two wires are twisted together (the twisting prevents interference problems) to form a pair, and the pair forms a circuit that can transmit data. A cable is a bundle of one or more twisted pairs surrounded by an insulator. Unshielded twisted-pair (UTP) is the most commonly used type of twisted-pair cable. Shielded twisted-pair (STP) provides protection against cross-talk. Twisted-pair cable is now commonly used in Ethernet, Fast Ethernet, token ring, and other network topologies. See also CAT 5.

A cable consisting of individual conductors twisted in pairs around each other. The purpose of twisting the conductors around each other is to reduce the affects of crosstalk.
