How to strip the wires from a 4-core optical cable

Stripping a 4-core optical cable requires careful, stepwise removal of the outer jacket, aramid fibers, and individual fiber coatings using specialized tools to avoid damaging the fibers.

Tools You Will Need

• Fiber optic cable stripper with multiple grooves for different coating sizes
• Kevlar or aramid scissors for cutting strength fibers
• Utility knife or precision cutter for the outer jacket (optional for thick jackets),
• Lint-free wipes and alcohol for cleaning
• Needle-nose pliers (optional for handling fibers),

Step-by-Step Process

1. Prepare Your Workspace Ensure a clean, well-lit area free of dust and debris. Lay out all tools within easy reach and inspect the cable for damage or kinks . 2. Cut the Cable to Length Use kevlar scissors to cut the cable cleanly at the desired point. This prevents fraying and makes stripping easier . 3. Strip the Outer Jacket

• Use the largest groove on your fiber optic stripper or a utility knife to carefully cut around the outer jacket.
• Remove approximately 2 inches (50mm) of the jacket, taking care not to nick the underlying aramid fibers .
• If using a spiral or helical cutter, rotate the tool around the cable to make a clean cut . 4. Remove Aramid (Kevlar) Fibers
• After the jacket is removed, cut the exposed aramid fibers close to the jacket end using kevlar scissors.
• Bundle the fibers together to make handling easier . 5. Strip Individual Fiber Coatings
• Use the appropriate groove on the fiber stripper for the 900-micron buffer first, removing it in small increments (about 6–8mm at a time) to reduce stress on the fiber .
• If the cable has a secondary coating (e.g., 250-micron), use the smallest groove to remove it in similar small steps .
• Hold the stripper at a 45-degree angle to minimize fiber stress and prevent breakage . 6. Clean the Fibers
• Wipe the stripped fibers with a lint-free cloth and alcohol to remove debris and residue .
• Inspect the fiber ends with a microscope or visual fault locator to ensure they are clean and undamaged . 7. Repeat for Each Fiber
• For a 4-core cable, repeat the stripping, cleaning, and inspection process for each fiber individually to ensure consistent preparation .

Safety and Best Practices

• Always wear cut-resistant gloves when handling sharp tools .
• Take small, controlled cuts rather than trying to remove large sections at once .
• Dispose of fiber scraps in a marked container to prevent injury .
• Maintain your stripping tools to keep cutting edges sharp and precise . By following these steps, you can safely strip a 4-core optical cable while preserving the integrity of the fibers for termination or splicing.
