Horizontal backbone cable pools should not exceed how many feet between pull points?

Horizontal backbone cable pools should not exceed how many feet between pull points?

• A. 98
• B. 72
• C. 120
• D. 50

Answer: (A)

Distance between pull points is limited to keep pulling tension and bending within safe, installable limits. For horizontal backbone cabling, the pool between pull points should be kept to a specific maximum so you can pull the cable without overstressing it or kinking it, and so you have enough slack to enough feed through bends and conduits. The number chosen in this topic is 98 feet, which reflects the standard used in training to ensure pulling is feasible and the cable remains within its allowable tension and bend-radius requirements. Going shorter would create more pull points than necessary; going longer risks exceeding the cable’s pulling limits and potential damage.
