foiled twisted pair (FTP)

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).

FTP cable with foil shield

ing Since it is not clear from the designation FTP cable whether the individual wire pairs have a foil shielding or whether all wire pairs are jointly surrounded by an overall foil shielding, 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.
