How to coil 8-core fiber optic cable onto a spool

Coil the 8-core fiber optic cable carefully, maintaining the minimum bend radius, avoiding tension or kinks, and using a level-wind or traverse winding system for neat, secure spooling.

Preparation and Precautions

Before coiling, inspect the spool and cable: ensure the reel flanges are free of debris, bolts are tight, and the spool is stable. Wear appropriate personal protective equipment such as gloves and eyewear. Avoid excessive pulling, bending, or crushing forces, as fiber optic cables are sensitive and can be damaged, affecting transmission performance . Always consult the cable specification sheet for the minimum bend radius and maximum tensile load.

Coiling Method

  1. Calculate Reserved Length: Determine the length of fiber needed for splicing or future deployment. Pre-process the cable and pigtails to ensure uniformity .
  2. Start Coiling: Begin at one end of the cable. Coil the fiber gradually onto the spool, keeping the cable aligned and avoiding sharp bends. Maintain the minimum bend radius throughout .
  3. Use Level-Wind or Traverse Drive: For precise and even spooling, use a traverse winding system (like the Amacoil/Uhing Kinemax) to control the linear pitch and reversal points. This ensures the fiber is evenly distributed across the spool without overlapping or tangling .
  4. Secure the Fiber: Fix the cable at the start and end points to prevent unwinding. If coiling multiple fibers, coil them individually or in small groups to avoid confusion and maintain organization .
  5. Special Situations: If fibers are unusually long or short, coil them separately at the ends. For fibers with heat-shrink sleeves or splices, coil them first in the fixing groove to protect joints .

Final Checks

  • Ensure the fiber is neatly coiled without kinks or sharp bends.
  • Verify that the spool is stable and the fiber is evenly distributed.
  • Label the spool if necessary for identification and future maintenance. By following these steps, the 8-core fiber optic cable will be coiled safely, maintain optical performance, and be ready for storage or deployment .
