What is the maximum pull tension for high-performance cable?

• A. 15 ft-lbs
• B. 25 ft-lbs
• C. 35 ft-lbs
• D. 45 ft-lbs

Answer: (B)

Pulling tension is the force you apply to a cable as you pull it into place. High‑performance cables have delicate components—thin insulation, tight fiber wraps, and thin jackets—that can be damaged by excess force, even if the damage isn’t visible right away. Manufacturers set a maximum pulling tension to keep from overstretching, microbending the fibers, or crushing the jacket, all of which can degrade signal quality or cause premature failure. For high‑performance installations, 25 ft‑lbs is the commonly specified limit. That value reflects a balance between getting the cable through pathways and protecting its integrity during the pull. Pushing beyond that can increase the risk of fiber damage or performance loss, while staying at or below it helps ensure the cable remains within spec after installation. In practice, use a tension gauge and maintain suitable slack and smooth bends to stay under this limit.
