Question 3

Describe the three different types of cabling recognized by TIA/EIA as acceptable for horizontal wiring.

Accepted Answer

TIA/EIA recognizes three possible cabling types for horizontal wiring: UTP,STP,or fiber opticcable.UTP (unshielded twisted pair)cable is a type of copper-based cable thatconsists of one or more insulated twisted-wire pairs encased in a plastic sheath.STP (shielded twisted pair)cable is atype of copper-based cable containing twisted-wire pairs that are not only individuallyinsulated,but also surrounded by a shielding made of a metallic substance such as foil.Fiber-optic cable is a form of cable that contains one or several glass or plastic fibers inits core and comes in two types: single-mode fiber (SMF)or multimode fiber (MMF).Copper-based cable transmits data via electric signals,and fiber-optic cable transmitsdata via pulsing light sent from a laser or light-emitting diode (LED).
