Horizontal four-pair cable is normally run between which components?

• A. From the TR to a single work area outlet on one floor
• B. A TR and each work area outlet on one or more floors
• C. From the TR to the data closet on a different floor
• D. From the service entrance to the TR

Answer: (B)

Horizontal cabling carries the network from the telecommunications room out to every work-area outlet on the floor. The four-pair cable used (typically Cat5e/6) connects the TR to each outlet so that each desk or device has a drop without extra looping or cross-connections. This is different from backbone cabling, which vertically links TRs and data closets across floors, and from service-entrance wiring, which feeds the building rather than distributing to individual outlets. So the intended path is from the TR to each work-area outlet on one or more floors.
