Shielded twisted pair (STP) is a type of copper wiring used in Ethernet networks, especially fast data rate Ethernets. In the shielded twisted pair, each of the two copper wires that are twisted together are coated with an insulating coating that functions as a ground for the wires. The extra covering in shielded twisted pair wiring protects the transmission line from electromagnetic interference leaking into or out of the cable.
