What is an Unshielded Twisted Pair (UTP)? - Definition Unshielded twisted pair (UTP) is a ubiquitous type of copper cabling used in telephone wiring and local area networks ( LANs ). There are five types of UTP cables -- identified with the prefix CAT, as in category -- each supporting a different amount of bandwidth. What is an Unshielded Twisted Pair Cable (UTP) Cable Unshielded Twisted Pair Cable: Unshielded twisted pair (UTP) cables are widely used in the computer and telecommunications industry as Ethernet cables and telephone wires. In an UTP cable, conductors which form a single circuit are twisted around each other in order to cancel out electromagnetic interference (EMI) from external sources. Twisted pair - Wikipedia OverviewExplanationHistoryUnshielded twisted pairTypesTwisted pair cabling is a type of wiring in which two conductors of a single circuit are twisted together for the purposes of improving electromagnetic compatibility. Compared to a single conductor or an untwisted balanced pair, a twisted pair reduces electromagnetic radiation from the pair and crosstalk between neighboring pairs and improves rejection of external electromagnetic interference. It was invented by Alexander Graham Bell.See more on enpedia · Text under CC-BY-SA license Chapter 4: Cabling - FCIT Unshielded Twisted Pair Connector The standard connector for unshielded twisted pair cabling is an RJ-45 connector. This is a plastic connector that looks like a large telephone-style connector (See fig. 2). A slot allows the RJ-45 to be inserted only one way. Cat6a Shielded vs. Unshielded: Which Is Better? | FS Community Cat6a Unshielded Cable. Cat6a unshielded twisted pair (UTP) cables are twisted into 4 sets of pairs. Each bare copper conductor is insulated and color coded. Each bundle of Cat6a unshielded cables is bundled under an overall jacket such as PVC, and each pair of cable has a different twist rate in order to minimize crosstalk within the cable. Shielded and unshielded twisted-pair cable revisited Shielded and unshielded twisted-pair cable revisited. Recently, the advantages and disadvantages of shielded and unshielded twisted-pair cable have been under debate. Advocates of STP cable, which includes screened twisted-pair and foil twisted-pair cables, claim that it is superior to UTP cable.
