Stripping techniques for optical cables using double steel wires

Stripping double steel wire optical cable requires specialized tools and careful technique to remove protective layers without damaging the fiber core.Cable StructureDouble steel wire optical cables typically consist of:Outer jacket: Protective polymer layerSteel wire strength members: Provide tensile strengthBuffer coating: Secondary protective layer around the fiberPrimary acrylate coating: Directly protects the glass fiberGlass core and cladding: The actual optical fiber transmitting signals The steel wires add mechanical strength but make stripping more challenging compared to standard fiber cables.Tools for StrippingManual Fiber Strippers: Precision tools with laser-drilled or ground notches to remove buffer and acrylate coatings without touching the glass fiber .Wire Cutters and Strippers for Steel Members: High-carbon stainless steel blades or spring-assisted pliers can cut through steel wires and outer jackets without crushing the fiber .Semi-Automated or Automated Machines: Machines like the Cut & Strip Family or PowerStrip series can handle multi-layered cables, including steel-reinforced optical cables, providing consistent and repeatable stripping while reducing operator error .Stripping TechniqueStep 1: Remove Outer Jacket – Use a suitable wire stripper or cutting tool to carefully cut the outer polymer jacket without nicking the steel wires or fiber.Step 2: Cut Steel Strength Members – Use wire cutters designed for steel to trim the strength members, exposing the buffer layer.Step 3: Strip Buffer and Primary Coating – Use a fiber optic stripper to remove the buffer and acrylate coating down to the 125µm cladding, ensuring a clean, straight cut .Step 4: Inspect Fiber – Check for nicks, scratches, or residual coating. Any damage can cause signal loss or connection failure.Safety and Best PracticesAlways wear safety glasses to protect against flying steel fragments.Avoid using generic wire strippers or knives on the fiber; improper tools can create micro-cracks in the glass .Clean stripping tools after use to remove coating residue and maintain precision .For large-scale or repetitive work, consider automated stripping machines to improve efficiency and consistency . Using the correct tools and following proper techniques ensures the optical fiber remains intact, maintains signal integrity, and allows for reliable splicing or connector termination.
