How to remove the outer sheath of a fiber optic pigtail

Use a fiber optic cable stripper or specialized scissors to carefully remove the outer sheath without damaging the inner fiber.

Tools Needed

• Fiber optic cable stripper (e.g., CFS-2 or RCS-0425) or wire stripper suitable for 2–3 mm jackets
• Cable-cutting scissors for aramid yarn or buffer removal
• Needle-nose pliers (optional) for pulling off the sheath
• Safety glasses to protect eyes from fiber shards

Step-by-Step Procedure

1. Measure and Mark Determine the length of the outer sheath to strip according to your connectorization or splicing requirements. Mark the strip point on the pigtail.
2. Adjust the Stripping Tool Set the blade depth on your fiber optic stripper to match the thickness of the outer sheath. For tools like the RCS-0425, rotate the adjustment knob to control cutting depth .
3. Make the Cut Place the stripper around the cable at the marked point. For spiral or ring-cut tools, rotate the tool around the cable to score the sheath evenly . Ensure the blade only contacts the sheath and not the inner fiber to avoid nicks or scratches .
4. Remove the Sheath Gently pull off the scored outer jacket using your fingers or needle-nose pliers. The sheath should come off cleanly, exposing the aramid yarn and buffer layers underneath .
5. Trim Aramid Yarn Use cable-cutting scissors to trim any exposed aramid fibers, leaving the inner buffer intact .
6. Inspect the Fiber Check the exposed fiber for any nicks or damage. A clean, straight cut ensures reliable performance and prevents future fiber failure .

Tips and Best Practices

• Always strip progressively, removing each layer individually (jacket, aramid yarn, buffer) to avoid damaging the fiber .
• Keep tools sharp and well-maintained to ensure clean cuts .
• Perform a bend test on the stripped fiber to detect any hidden damage before connectorization .
• Work in a well-lit area and wear safety glasses to prevent injury from fiber shards . By following these steps and using the proper tools, you can safely and efficiently remove the outer sheath from a fiber optic pigtail while preserving the integrity of the inner fiber.
