Fiber optic cable cannot be stripped of optical fiber

If a fiber optic cable cannot be stripped, it is usually due to improper tools, incorrect technique, or the cable's multi-layer construction requiring careful, progressive stripping.Common Reasons Fiber Optic Cable Cannot Be StrippedIncorrect or dull stripping tools: Fiber optic cables require specialized strippers designed for the specific buffer or jacket diameter. Using a standard wire stripper or a dull blade can prevent proper removal and risk damaging the fiber underneath .Multi-layer cable construction: Many fiber optic cables have multiple layers, including the outer jacket, aramid yarn (Kevlar), and buffer coatings. Each layer must be stripped individually and progressively. Attempting to remove all layers at once can make stripping impossible or damage the fiber .Improper technique: Not fully closing the fiber stripper or applying uneven pressure can leave the coating intact. Some strippers require a precise blade depth adjustment for the specific cable diameter .Cable condition: Kinks, bends, or damage to the cable can make stripping difficult. Inspect the cable for defects before attempting to strip .Best Practices for Stripping Fiber Optic CablesUse the correct stripper: Match the stripper to the fiber type (tight buffer 900 µm, buffered 250 µm, or jacketed cable) and adjust the blade depth according to manufacturer guidelines .Progressive stripping: Remove the outer jacket first, then the aramid yarn, and finally the buffer coating. Avoid cutting or nicking the fibers .Clean and inspect: After stripping, clean the fiber with alcohol wipes and inspect with a microscope or visual fault locator to ensure the fiber is undamaged .Secure the cable: Use a cable clamp or grip to prevent the inner fiber from being pulled out during stripping .Practice safety: Always wear eye protection and work in a clean, well-lit area to avoid injury from sharp fiber ends . By following these steps and using the proper tools, most issues with fiber optic cables that cannot be stripped can be resolved, ensuring a clean and safe termination or splicing process.
