Horizontal stripping of outdoor optical cables

Horizontal stripping of outdoor optical cables involves using specialized fiber cable slitters or armored cable strippers to remove the outer jacket or armor safely without damaging the internal fibers.

Tools for Horizontal Stripping

Fiber cable slitters are precision tools designed to cut or open the outer jacket of optical cables along their length. They are suitable for multicore, sheathed, or armored outdoor cables and allow controlled cutting depth to prevent fiber damage. Common types include mid-span slitters, jacket slitters, and armored cable slitters, often made with hardened SK5 steel or tungsten carbide blades for durability and precision.

Armored cable strippers can rotate the blade 90 degrees, enabling both circular and longitudinal (horizontal) cuts. This feature allows technicians to strip the cable jacket or armor efficiently while maintaining stability and reducing labor effort. Ergonomic designs with reinforced grips or anodized aluminum bodies improve handling during field operations.

Stripping Procedure

Measure and mark the section of cable to be stripped. Adjust the cutting depth on the slitter or stripper to match the cable jacket thickness, ensuring the internal fibers are not nicked. Position the cable in the tool groove and move the slitter along the cable length for a clean horizontal cut.

Remove the jacket or armor carefully, exposing the internal fibers or buffer tubes for splicing or termination. Inspect the fibers for any damage before proceeding with splicing or connectorization.

Best Practices

Use precision tools to avoid scratching or nicking the optical fibers. For outdoor cables, follow industry standards such as Telcordia GR-20 for mechanical and environmental requirements. Ensure ergonomic handling to reduce fatigue during long installations.

For flat drop or specialty cables, consider FTTX-specific kits that include scribes, cleavers, and strippers for efficient preparation. By using the correct tools and following proper procedures, horizontal stripping of outdoor optical cables can be performed safely, efficiently, and in compliance with professional cabling standards.
