what is twisted pair cable
Twisted-pair cable. A twisted-pair cable is a cable made by intertwining two separate insulated wires. There are two twisted pair types: shielded and unshielded. A Shielded Twisted Pair (STP) has a fine wire mesh surrounding the wires to protect the transmission; an Unshielded Twisted Pair (UTP) do not.Shielded cable is used in older telephone networks, as well as network and data communications to reduce outside interference.
