Page Content

To remove a broken fiber optic cable at an SC cold splice, carefully cut out the damaged section, strip back the jacket and buffer, and prepare the fiber ends for splicing or termination.

Safety and Preparation

Before starting, wear safety glasses to protect against glass shards, and ensure the work area is clean and well-lit. Gather the necessary tools: fiber optic cutters, jacket strippers, alcohol wipes, and a precision cleaver if needed .

Step-by-Step Removal Process

  1. Locate the Break Identify the exact point of the break at the SC cold splice. Use a visual inspection or a visual fault locator to confirm the damaged section .
  2. Cut Out the Damaged Fiber Using kevlar shears or a fiber optic cutter, remove the broken portion of the cable. Make a clean cut to create a smooth working edge for the splice .
  3. Strip the Outer Jacket Slide the SC connector boot off the cable if present. Use a three-hole jacket stripper to remove approximately 2 inches (50 mm) of the outer jacket, exposing the internal fiber strands .
  4. Remove the Buffer and Yarn Carefully separate the internal yarn from the fiber strand. Strip the inner coating from the fiber using the jacket stripper or a precision fiber stripper, following the recommended strip length for your connector or splice .
  5. Clean the Fiber Ends Wipe the exposed fiber strands with alcohol wipes to remove any dirt or debris. This ensures a clean surface for splicing or re-termination .
  6. Prepare for Splicing or Re-termination
    • For mechanical splicing, insert both fiber ends into the splice holder and secure with the locking mechanism. Apply index-matching gel if required .
    • For fusion splicing, cleave the fiber ends to precise lengths using a cleaver, then align and fuse them with a fusion splicer. Protect the splice with a heat-shrink sleeve .
  7. Final Checks After removal and preparation, test the fiber with a visual fault locator or fiber optic meter to ensure the ends are clean and ready for reconnection .

Additional Tips

  • Keep the removed fiber pieces in a safe container to avoid injury.
  • If the splice is outdoors, consider using a waterproof cap or protective casing to prevent environmental damage .
  • Always follow manufacturer instructions for SC connectors and splice kits to maintain signal integrity. By following these steps, the broken fiber at the SC cold splice can be safely removed and prepared for repair, minimizing signal loss and ensuring a reliable reconnection.
