Optical Ground Wire (OPGW) and other fiber optic cables are highly sensitive and require specific "Cable Rigging Accessories" to prevent damage to their delicate internal fibers:

• Specialized OPGW Pulling Grips/Socks: Designed to evenly distribute gripping force over the metallic outer sheath without crushing the inner optical core.

• Large Radius Sheaves/Blocks: Rigging blocks with larger diameters and ultra-smooth, often non-metallic (e.g., polyurethane, nylon) linings to minimize bending stress and surface abrasion on the cable.

• Anti-Twist Swivels: High-quality, low-friction swivels designed to prevent any torsional stress from being transferred to the OPGW during lifting or pulling.

• Precise Load Limiting Devices: Often integrated into the pulling system or as standalone accessories, ensuring that pulling tension never exceeds the OPGW's specified limits.

These accessories are vital for preserving the integrity and performance of fiber optic cables.
