The guideline stating that horizontal pulls between pull points should be no longer than 98' applies to which portion of the cabling?

• A. Vertical cabling
• B. Backbone cabling
• C. Horizontal runs
• D. Riser cabling

Answer: (C)

The guideline about horizontal pulls between pull points is about how you install the cables in the part of the system that runs from the telecom room to the work areas. This portion, called horizontal cabling, is what you actually pull through walls, ceilings, and conduits. Keeping each pull under about 98 feet helps limit pulling tension, reduces the risk of damaging the cable (kinks, stretching, or crush through bends), and makes installation safer and more reliable. This rule doesn’t typically apply to vertical cabling (between floors), backbone cabling (connecting different telecommunications rooms), or riser cabling (vertical runs within a building that have special fire/conditioning considerations), which have their own installation guidelines. So plan the horizontal runs with pull points and segments short enough that no single pull exceeds the 98-foot guideline.
