Fiber optic cable installation is governed by a set of technical guidelines that focus on preserving the cable's optical integrity. Some of the most widely referenced standards and guidelines include:

• Maximum Pulling Tension: Unlike power cables, which are pulled with kilonewtons of force, most fiber optic cables have a maximum installation pulling tension of around 2,700 Newtons (600 pounds) for outdoor cables. Our hydraulic cable pullers are equipped with tension monitoring systems to ensure this limit is never exceeded.

• Minimum Bend Radius: This is a critical factor. The standard is typically 20 times the cable's outside diameter during a pull (dynamic) and 10 times the outside diameter when stationary (static). Bending the cable too tightly can cause microbends in the fiber, leading to signal loss. Our underground-Cable-Laying-Equipment-and-Tools.html target='_blank'>cable rollers and sheaves are designed to provide a smooth, controlled path that respects these bend radius limits.

• Telcordia GR-20-CORE: This is a comprehensive industry standard in North America for qualifying the performance and reliability of outside plant (OSP) optical fibers and cables. Adherence to this standard ensures the cable can withstand the rigors of installation and a long service life.
