Page Content

Opening a network or fiber optic cable requires careful stripping of the outer jacket using specialized tools to avoid damaging the internal fibers or conductors.

Tools Needed

  • Fiber optic stripper for removing the protective jacket without nicking the fiber core .
  • Kevlar cutter to trim strength members inside fiber cables .
  • Utility knife or cable jacket stripper for copper network cables.
  • High-precision cleaver for fiber ends if splicing is required .
  • Protective gloves and safety glasses to prevent injury from sharp fibers or tools.

Steps for Fiber Optic Cables

  1. Visual Inspection: Check the cable for visible damage or kinks before opening .
  2. Locate the Section to Open: Identify the area where the cable needs to be accessed or repaired.
  3. Cut the Outer Jacket: Use a fiber optic stripper or utility knife to carefully remove the outer jacket without cutting the fibers inside .
  4. Trim Strength Members: Cut Kevlar or aramid fibers with a Kevlar cutter to expose the inner fibers .
  5. Remove Protective Coating: Strip the buffer coating from the fiber to expose the bare glass for splicing or testing .
  6. Handle Fibers Carefully: Avoid bending fibers sharply or scratching the core, as this can cause signal loss .

Steps for Copper Network Cables

  1. Measure and Mark: Determine the length of jacket to remove.
  2. Score the Jacket: Use a cable stripper to score around the circumference of the cable.
  3. Remove the Jacket: Gently pull off the outer jacket to expose twisted pairs inside.
  4. Separate Pairs: Untwist and straighten the pairs for termination or testing.

Safety Tips

  • Always work slowly and steadily to prevent accidental cuts or fiber breakage .
  • Cap exposed fiber ends to prevent contamination or injury .
  • Avoid applying lateral force or twisting the cable, which can damage internal components .
  • For complex or high-fiber-count cables, consider professional training or guidance to prevent costly mistakes . By following these steps and using the proper tools, you can safely open network or fiber optic cables for repair, splicing, or installation while minimizing the risk of damage or injury.
