Twisted pair cabling has been around since the days of Alexander Graham Bell and is still used today to transmit landline telephone signals. As the name implies, twisted pair cabling involves two pairs of metal wires wrapped around each other to prevent electromagnetic interference. A variation of twisted pair cable is unshielded twisted pair (UTP) cable where no shielding is used to surround the copper wires. UTP cable is commonly used in Ethernet networks such as computer and video distribution systems.
