What is Shielded Twisted Pair (STP)?<\/strong><\/p>\n Shielded twisted pair (STP) is a special type of copper telephone and local area network (LAN) cabling used in some commercial installations. It adds an outer jacket or shield to the ordinary twisted pair cable, which acts as a ground.<\/p>\n Twisted pair is the common copper wire that connects many computer networks and telephone companies. To reduce crosstalk, or electromagnetic induction, between the paired wires, two insulated copper wires are twisted around each other. Each signal on a twisted pair requires two wires.<\/p>\n Unlike unshielded twisted pair (UTP), shielded twisted pair also wraps the wires in a shield and grounds them to further reduce electromagnetic and radio frequency interference. STP cable is more expensive and more difficult to install than UTP cabling.<\/p>\n Unshielded twisted pair<\/strong><\/p>\n Shielded twisted pair cable has an additional outer shield added to the standard twisted pair cable.<\/p>\n
