Twisted Copper Pair

Twisted Copper Pair


Twisted Copper Pair, or Twisted Pair Cable, is a type of cable that consists of two independently insulated wires twisted around one another. The use of two wires twisted together helps to reduce crosstalk and electromagnetic induction. While twisted copper pair is used by older telephone networks and is the least expensive type of LAN (Local-Area Network) cable, most networks contain some twisted-pair cabling at some point along the network.
