Stripping of round optical cables

Stripping round optical cables involves carefully removing the outer jacket, aramid yarn, and fiber coatings using specialized tools to expose the bare fiber without causing damage.Tools for Stripping Optical CablesFiber Strippers: Precision tools designed to remove polymer coatings (acrylate, silicone, polyimide) from fibers, exposing the glass core without scratches or nicks. They come in mechanical, thermal, or non-contact types and are often adjustable for different fiber diameters and coating thicknesses ( ).Cable Strippers and Scissors: Tools like the CFS-2 or RCS-0425 allow stripping of outer jackets and insulation layers of round cables, including PVC or low/medium voltage optical cables. They use slots or blades to cut the sheath and can handle diameters from 2 mm up to 25 mm or more ( ).Advanced Multi-Action Tools: Tools such as the CST-4000 enable longitudinal, spiral, and circular cuts for large round cables (19–40 mm), with adjustable spring-loaded blades for precise stripping ( ).Stripping ProcessPreparation: Work in a clean, well-lit area. Inspect the cable for damage, kinks, or bends before stripping ( ).Outer Jacket Removal: Use a cable stripper to make a radial or spiral cut around the cable. Carefully remove the jacket to expose the aramid yarn or buffer layers ( ).Aramid Yarn and Buffer Stripping: Remove aramid fibers carefully to avoid damaging the inner fibers. For multi-layer cables, strip each layer progressively, starting with the jacket, then yarn, then buffer ( ).Fiber Coating Removal: Use a fiber stripper to remove the polymer coating from the glass fiber. Adjust the blade depth according to the fiber diameter and coating type. Typical strip lengths are 30–40 mm, but avoid exceeding 50 mm at a time to prevent fiber damage ( ).Cleaning and Inspection: Clean the bare fiber with high-purity alcohol or a dedicated fiber cleaner. Inspect the fiber end with a microscope or visual fault locator to ensure it is free of scratches, nicks, or debris ( ).Cleaving: Use a fiber cleaver to create a clean, perpendicular end face for splicing or connectorization ( ).Best PracticesAlways maintain sharp cutting edges on strippers to prevent fiber damage ( ).Strip fibers progressively in multi-layer cables to avoid nicking inner layers.Use protective caps or sleeves on stripped fibers until termination to prevent contamination ( ).For large or armored cables, consider specialized slitting tools to handle polyethylene or metal armor efficiently ( ).By following these steps and using the appropriate tools, technicians can achieve clean, precise, and safe stripping of round optical cables, ensuring reliable fiber terminations and optimal network performance.
