How to strip the layers from an optical fiber cable

Use a precision fiber optic jacket stripper or sheath stripper to safely and efficiently remove the outer layer without damaging the underlying fibers.

Tools for Quick Stripping

Mechanical Fiber Strippers: Handheld tools with sharp, sized slots for the outer jacket, primary coating, or secondary coating. They allow you to hold the cable, press the jaws, and slide the jacket off cleanly. Sheath Strippers: Designed for larger cables or microcables, these tools can strip jackets up to 3.

5mm quickly and often include adjustable blade depth for precision. Kevlar Scissors: Used to cut aramid yarn or strength members after the jacket is removed.

Thermo-

Mechanical Strippers: Use heat to soften the jacket before removal, reducing the risk of nicking the fiber.

Step-by-

Step Procedure

Prepare the Work Area: Ensure a clean, well-lit space free of dust and debris. Lay out all tools within reach. Select the Correct Tool and Slot: Match the stripper slot to the cable diameter to avoid cutting underlying aramid yarn or fiber.

Adjust Blade Depth: For sheath strippers, set the blade depth to just penetrate the outer jacket without touching the fibers. Make a Circumferential Cut: Place the tool around the cable at the desired strip length and rotate it in a spiral or circular motion to cut the jacket. Remove the Jacket: Pull off the cut section using fingers or needle-nose pliers.

Ensure the edge is clean and not torn. Trim Strength Members: Use Kevlar scissors to cut exposed aramid yarn if necessary.

Tips for Efficiency and Safety

Always maintain sharp cutting edges to prevent tearing or crushing the jacket. Strip each layer progressively—outer jacket first, then aramid yarn, then buffer coatings—to avoid fiber damage. Inspect the stripped area for any nicks or cuts in the fibers before proceeding with termination or splicing.

For midspan stripping, a helical or spiral cut with a sheath stripper is ideal for clean removal. Using the right tool and following these steps ensures fast, clean, and safe removal of the outer layer, minimizing the risk of fiber damage and improving the quality of terminations or splices.
