Network Cable Types and Specifications

UTP: (Unshielded Twisted Pair)

Short for unshielded twisted pair, a popular type of cable that consists of two unshielded wires twisted around each other. Due to its low cost, UTP cabling is used extensively for  and telephone connections. UTP cabling does not offer as high  or as good protection from interference as or , but it is less expensive and easier to work with.

STP: (Shielded Twisted Pair)

Often abbreviated STP, a type of copper telephone wiring in which each of the two copper wires that are twisted together are coated with an insulating coating that functions as a ground for the wires. The extra covering in shielded twisted pair wiring protects the transmission line from  leaking into or out of the cable. STP cabling often is used in  networks, especially fast data rate Ethernet.

Fiber optic:

Fiber optic cabling consists of a center glass core surrounded by several layers of protective materials  It transmits light rather than electronic signals eliminating the problem of electrical interference
