Use a precision fiber optic stripper to carefully remove the outer sheath without damaging the inner fibers, following a progressive layer-by-layer approach.

Tools and Safety

• Fiber optic cable stripper: Choose a professional-grade stripper with a notch suitable for the outer jacket diameter (typically 1.6–3mm for multi-core cables) to avoid cutting the inner fibers .
• Cable-cutting scissors or pliers: For trimming aramid yarn or other strength members .
• Safety glasses: Protect your eyes from sharp fiber fragments .
• Clean workspace: Ensure a dust-free, well-lit area to prevent contamination .

Step-by-Step Procedure

1. Measure and mark the strip length: Determine how much of the outer sheath needs to be removed for your termination or splicing application.
2. Adjust the stripper blade depth: Set the fiber optic stripper to the correct depth for the outer jacket, ensuring it will cut the sheath but not the aramid yarn or buffer layers underneath .
3. Make a radial cut: Place the stripper at the marked point and rotate it around the cable in a spiral or circular motion to score the outer sheath evenly .
4. Remove the outer sheath: Gently pull off the scored jacket using your fingers or needle-nose pliers. The cut edge should be clean and straight, not jagged or torn .
5. Inspect the aramid yarn: Check for any damage to the strength fibers. If any fibers are cut, adjust the stripper to a larger gauge and repeat the process .
6. Trim aramid yarn: Use cable-cutting scissors to cut the exposed aramid yarn flush with the stripped end, taking care not to nick the inner fibers .

Additional Tips

• Progressive stripping: For multi-layer cables, strip each layer individually—outer jacket first, then aramid yarn, then buffer coatings—avoiding a single-step removal .
• Avoid generic tools: Do not use standard wire strippers or knives, as they can damage the delicate glass fibers and cause signal loss .
• Clean the stripped end: Use alcohol wipes to remove debris before further termination or splicing . By following these steps and using the correct tools, you can safely and efficiently strip the outer sheath of an 8-core optical cable while preserving the integrity of the inner fibers for optimal performance.
