Method for installing fiber optic coil flange

Proper installation of a fiber optic coil flange involves securely mounting the cable reel, maintaining the minimum bend radius, and using figure-8 coiling to prevent twisting and damage.

Preparation and Safety

Before installation, inspect the cable reel for physical damage and ensure the cable ends are capped to prevent contamination or moisture ingress. The installation area should be clear of sharp objects, debris, or obstacles that could damage the cable. Ensure the ambient temperature is above the minimum recommended for handling the cable, typically above 5°C, and allow the cable to acclimate if necessary.

Mounting the Reel on the FlangePosition the reel so that the flange is perpendicular to the mounting surface. Use a shaft through the center of the reel and a spreader beam to lift and secure it. Secure the reel with wedges or clamps to prevent movement during installation.

If multiple reels are used, they can be cross-stacked for stability. Ensure the forks or supports are placed under the reel and remain perpendicular to the flange to prevent tilting or uneven rotation.

Coiling and Cable Deployment

Use figure-8 loops when uncoiling the cable to prevent twisting. The figure-8 configuration introduces a half twist on one side and removes it on the other, maintaining fiber integrity. Loop sizes typically range from 1.

5 m to 4 m depending on cable stiffness. Never exceed the cable's minimum bend radius. For example, multiply the cable diameter by 15 to determine the working bend radius.

Pull the cable, do not push, and always use the cable's strength members (Kevlar or fiberglass rods) to bear tension. For long runs, consider using lubricants compatible with the cable jacket and automated pullers with tension control to prevent overloading.

Monitoring and Communication

Assign personnel to monitor the supply reel, pulling equipment, and cable path to prevent sudden jumps or kinks. Communicate along the installation path to coordinate tension adjustments and ensure smooth deployment. Post-InstallationAfter installation, secure the cable ends and document the installation, including reel data, bend radius compliance, and any deviations from the plan.

Inspect the cable for any signs of mechanical stress or damage before final splicing or termination. By following these steps, the fiber optic coil flange can be installed safely, ensuring the cable remains undamaged and ready for reliable operation.
