Detailed explanation-1: -Shielded twisted pair (STP). These cables come with a braided, wired mesh that encases each pair of insulated copper wires.
Detailed explanation-2: -There are two main types of twisted pair cables, unshielded twisted pair (UTP), and shielded twisted pair (STP), which contains each pair of wires within an aluminium foil shield for further isolation. The impedance of a typical twisted pair is of the order of 100–150 .
Detailed explanation-3: -Twisted-Pair Cable Each twisted-pair wire consists of two separate insulated copper wires that are twisted together.
Detailed explanation-4: -Unshielded twisted pair (UTP) is a ubiquitous type of copper cabling used in telephone wiring and local area networks (LANs). The five types of UTP cables are identified with the prefix CAT, as in category, each supporting a different amount of bandwidth.
