How to separate steel strand optical cables

Separating steel strand optical cables requires careful removal of the steel messenger or armored layers using specialized tools while protecting the optical fibers inside.Understanding Steel Strand Optical CablesSteel strand optical cables typically consist of a steel messenger strand that supports the fiber and may include lashing wires or armored layers for protection . The steel strands are often made of carbon steel with zinc or zinc-aluminum coatings for corrosion resistance, and they are wrapped around a central wire. The optical fibers are either lashed to the steel strand or enclosed within an armored sheath .Tools RequiredCable Strippers: For removing the outer jacket without damaging fibers .Steel Tape Remover (STR): Specifically designed for armored or steel tape cables to safely cut and remove steel layers .Safety Equipment: Safety glasses and gloves to protect against sharp steel strands and fiber shards .Fiber Stripping Tools: For removing buffer coatings from the optical fibers after the steel layer is removed .Step-by-Step ProcedurePrepare the Work Area: Ensure a clean, well-lit workspace and wear safety glasses to protect your eyes from sharp steel strands and fiber shards .Remove the Outer Jacket: Use a cable stripper to carefully cut and peel back the outer polymer jacket of the cable, exposing the steel strands or armored layer .Separate Steel Strands:For messenger strands, unwind or cut the lashing wire carefully using pliers or a steel tape remover. Avoid pulling on the fibers directly .For armored cables, use an STR tool to cut and remove the steel tape layer without nicking the fibers inside .Expose Optical Fibers: Once the steel strands are removed, gently separate the optical fibers from the remaining strength members. Use fiber strippers to remove the buffer coating in preparation for splicing or termination .Handle Fibers Carefully: Avoid bending fibers beyond their minimum bend radius and keep them free from tension or crushing forces .Safety ConsiderationsAlways wear eye protection and gloves when handling steel strands and optical fibers .Dispose of fiber scraps properly to prevent injury.Avoid excessive pulling or bending of the cable to prevent fiber breakage . By following these steps and using the appropriate tools, you can safely separate steel strand optical cables and prepare the fibers for splicing, termination, or installation.
