The FTP cable (Foiled Twisted Pair) is a foil-covered cable
. It consists of four unshielded, twisted pairs of wires that are encased in a foil shield made of aluminum foil. Often the foil shielding is surrounded by a thermoplastic material. The outer jacket surrounding the foil shield is usually made of polyvinyl chloride
(PVC).ISO/IEC have changed the designation to F/UTP in 11801 (2002). The F/UTP cable consists of unshielded twisted pairs of wires protected by a foil shield. The electromagnetic shielding is achieved by twisting the wire pairs and the foil shield. Variants of the FTP cable are the S/FTP cable, which has a braided shield in addition to the foil shielding of the wire pairs, and the F/FTP cable, in which each individual twisted pair and the entire conductor strand are sheathed with a foil shield.
