In cabling technology, the acronym FTP stands for foiled twisted pair. Ethernet LAN is frequently supported by FTP networking cables. This type of twisted-pair wiring has two conductors of a single circuit twisted together to cancel out electromagnetic interference. FTP cabling is one of three main types of twisted-pair wiring. The other two are UTP and STP. Each twisted pair cable format provides an option for computer networking. UTP is unshielded wiring, while STP and FTP have shielding. Foiled twisted-pair cabling has an aluminium foil shield surrounding its wiring pairs, which provides protection against external interference. Networks installers can buy Cat5e FTP or Cat6 cable to gain the benefits of metallic shielding. FTP cables are advantageous when networks must operate in high noise settings. Though the UTP might be an appropriate choice for the home or office, an FTP cable would be preferred in an industrial environment for interference reduction.

FTP Cable Specifications

Within an FTP cable, pairs of insulated copper wires are twisted around one another to reduce crosstalk and interference. Foil is then wrapped around these wiring groups to meet the FTP specification. An S/FTP abbreviation may also be seen in descriptions of network cabling. This term stands for screened/foiled twisted pair. With this designation, the twisted pairs will be individually foil-shielded and then surrounded by an overall shield for additional protection. The appropriately chosen structured cabling in conjunction with active equipment will support security and performance in the data centre environment.
