How to strip optical cables longitudinally

Stripping optical fiber cables longitudinally requires careful, stepwise removal of the jacket, aramid fibers, and buffer coatings using specialized tools to avoid damaging the fiber.Step-by-Step Process1. Prepare the CableDetermine the length of cable to strip and mark the jacket accordingly. Allow extra length for slack and connectorization ( ).Use a piece of shrink sleeve or tape to protect the cable at the strip point if desired ( ). 2. Remove the Outer JacketScore the outer jacket circumferentially 7–10 inches from the cable end using a hook blade or fiber jacket cutter ( ).Carefully bend and peel off the jacket. For some cables, a ripcord can be used to pull off the remaining jacket ( ).Ensure the underlying aramid fibers are not damaged during this step ( ). 3. Cut Aramid YarnUse kevlar scissors to trim the aramid fibers close to the jacket end, bundling them for easier handling ( ).Avoid cutting too close to the fiber to prevent stress on the core ( ). 4. Strip the Fiber BuffersUse a fiber stripper with grooves matched to the fiber diameter (e.g., 900 µm and 250 µm) ( ).Strip the buffer in small increments (6–8 mm at a time) at a 45-degree angle to reduce stress ( ).If the stripper has multiple grooves, use progressively smaller grooves to remove each buffer layer without breaking the fiber ( ). 5. Clean the FiberWipe the stripped fiber with a lint-free cloth and alcohol to remove debris ( ).Special fiber optic cleaners can be used in the field, but alcohol and microfiber cloths are sufficient for practice ( ).Tools and TipsFiber Strippers: Ensure blades are sharp and matched to fiber diameter ( ).Kevlar Scissors: For cutting aramid yarn without fraying ( ).Bare Fiber Gripper: Provides a secure hold without microfractures ( ).Always strip layers progressively—jacket first, then aramid yarn, then buffers ( ).Take small cuts and avoid excessive force to prevent fiber cracks or breakage ( ).Safety and Best PracticesWork in a clean area and dispose of fiber scraps in a marked container ( ).Avoid touching the fiber core with bare hands to prevent contamination ( ).Practice is essential; breaking fibers is common initially, so take your time ( ). By following these steps and using the proper tools, you can safely strip optical cables longitudinally for splicing or connectorization while minimizing the risk of fiber damage ( ).
