How to remove the outer sheath from a 48-core optical cable

Use a specialized fiber optic cable stripper to carefully remove the outer sheath layer by layer, ensuring the inner fibers and aramid yarn remain undamaged.Tools RequiredFiber optic cable stripper (e.g., RCS-0425 or similar helical cutting tool) for large-diameter cables .Cable-cutting scissors for trimming aramid yarn .Needle-nose pliers or tweezers for removing the sheath after cutting .Protective gloves and eye protection to prevent injury from sharp fibers .Step-by-Step ProcedureMeasure and Mark the Strip LengthDetermine the length of the outer sheath to remove based on your installation or connectorization requirements.Mark the cable at the desired strip point.Adjust the Stripping ToolSet the blade depth on the fiber optic cable stripper to match the thickness of the outer sheath, typically up to 5 mm for large multi-core cables .Ensure the blade is sharp and properly maintained to avoid tearing the sheath.Make a Radial CutPlace the stripper around the cable at the marked point.Rotate the tool in a helical or spiral motion to cut through the outer jacket without touching the inner aramid yarn or fibers .For midspan stripping, the helical action allows clean removal without damaging the cable core.Remove the Outer SheathGently pull off the cut section of the jacket using your fingers or needle-nose pliers .Inspect the exposed aramid yarn to ensure no fibers are cut, as damaged yarn reduces tensile strength .Trim Aramid YarnUse cable-cutting scissors to trim the aramid yarn neatly, leaving the inner buffer tubes or fibers intact .Inspect the CableVerify that the inner fibers and buffers are undamaged.The edge of the stripped jacket should be clean and straight, not jagged or torn .Additional TipsProgressive Layer Stripping: For multi-layer cables, strip each layer individually—outer jacket first, then aramid yarn, then buffer tubes .Avoid Excessive Force: Do not bend, crush, or pull the cable sharply, as this can damage the fibers and affect transmission .Use Proper Tools: Automated or pre-configured stripping tools provide consistent results and reduce the risk of fiber damage . By following these steps and using the correct tools, you can safely strip the outer sheath of a 48-core optical cable while preserving the integrity of the inner fibers and aramid yarn.
