How to extract copper from optical fiber cables

Use specialized cable strippers and cutters to safely access and cut copper conductors in hybrid fiber-optic cables without damaging the optical fibers.Tools You Will NeedCable sheath stripper or ring cutter (e.g., Jonard JIC-4366) for removing the outer jacket and performing mid-span access on hybrid cables .Wire cutters or precision scissors for cutting copper conductors .Fiber optic strippers to protect the glass fibers while exposing copper .Safety gear: gloves and eye protection to prevent injury from sharp copper edges or fiber shards .Step-by-Step ProcessPrepare the Cable Identify the section of the cable where you need to access the copper. Ensure the work area is well-lit and ventilated. Wear gloves and safety goggles to protect against sharp fibers and copper edges .Remove the Outer Jacket Use a cable sheath stripper or ring cutter to slit the outer jacket. For mid-span access, adjust the tool to the cable diameter and rotate it around the cable to score the jacket without cutting the internal fibers .Expose the Copper Conductors After removing the outer jacket, you may encounter Kevlar or aramid fibers. Twist these fibers together and snip them with scissors to clear the path to the copper wires .Cut the Copper Wires Use wire cutters to snip the copper conductors to the desired length. Avoid crushing or bending the copper excessively, as this can affect conductivity .Protect the Fiber Optics While cutting copper, ensure the optical fibers remain untouched. Use fiber optic strippers to remove any protective coatings if necessary, but do not cut or score the glass fibers .Clean Up Collect all fiber scraps and copper shavings in a designated container to prevent injury or contamination .Tips for SuccessAlways score the jacket lightly before pulling it off to avoid damaging internal fibers.For figure-8 or webbed cables, use the slitting guide on the webbing to separate the copper and fiber sections cleanly .If precision is critical, consider using a fiber optic cleaver for the optical fibers while handling copper separately . By following these steps and using the proper tools, you can safely cut copper in optical fiber cables while preserving the integrity of the optical fibers and maintaining signal quality.
