Which type of cable is used for connection to work area outlets?

• A. Coaxial cable
• B. Four-pair UTP cable
• C. Fiber optic cable
• D. Single-pair UTP cable

Answer: (B)

Four-pair unshielded twisted pair is used to connect to work area outlets because this part of the cabling system (the horizontal cabling from the telecom room to the wall jack) is designed to carry modern Ethernet speeds using all four pairs. Using four pairs supports current standards like Gigabit Ethernet and beyond, and also enables PoE if needed. The other options don’t fit typical work area installations: coaxial cable is for legacy Ethernet or specialized feeds, fiber optic is generally reserved for backbone or long-distance/high-speed links requiring media conversion to reach work areas, and single-pair UTP isn’t the standard for Ethernet at office outlets.
