How to fix the optical cable reel

Proper installation and handling of an optical cable reel ensures smooth cable payout, prevents damage, and maintains signal integrity.

Preparing the Reel

Before installation, inspect the reel for structural integrity. Ensure the flanges, central drum, and bolts are intact and that the cable is wrapped symmetrically around the drum, respecting the minimum bending radius (MBR) of the fiber cable . During transport, always place reels in the upright roll position and secure them with wheel chocks or chains to prevent shifting . Avoid rolling reels long distances against the roll direction, as this can loosen the cable .

Positioning and Securing the Reel

• Place the reel on a cable reel support, trailer, or motorized reel stand.
• Apply the braking device to control rotation speed and prevent the cable from unspooling too quickly .
• For motor-driven reels, ensure the winding direction matches the motor's indicated arrow and that the cable is properly fixed to the moving part of the reel .

Cable Deployment

1. Lead the cable through pulleys or guides installed at towers or support points, maintaining proper tension .
2. Use a tension machine or tractor to pull the cable along the route, keeping tension low to avoid stretching or damaging the fiber .
3. Install clamps, rotating connectors, and transition devices at designated points to secure the cable .
4. Manage back-tension during payout to keep the top layer of cable tight on the reel .

Handling Common Issues

• Cable squirting: If the cable begins to squirt out of the feed hole, leave about one foot of the cable tail unsecured and cut excess length as needed. Do not tightly secure the tail, as this can cause reverse squirting .
• Flange bolts: Hand-tighten before payout and periodically retighten to maintain reel integrity .

Safety and Maintenance

• Always follow safety protocols, including protective covers on motorized reels and attention to moving parts .
• For outdoor installations, consider wind speed limits for motorized reels: stop operation if wind exceeds 35 m/s to prevent damage .
• After installation, secure the unused cable end to maintain tight wraps for future use . By following these steps, you can ensure a safe, efficient, and damage-free optical cable installation, whether using manual, spring-rewind, or motor-driven reels .
