Requirements for the stripping length of optical cables

The stripping length of an optical cable depends on the cable type and connector, typically ranging from 15 mm to 60 mm for different layers.

Typical Stripping Lengths

When preparing a fiber optic cable for termination, each layer must be stripped individually: Outer Jacket: Usually 50–60 mm (2–2. 5 inches) for standard patch cables, removed carefully to avoid damaging the underlying aramid yarn or buffer fibers. Aramid Yarn (Kevlar): Cut or pulled back after the jacket is removed; the length depends on the connector type but is generally slightly shorter than the jacket strip.

Buffer Coating: The fiber itself is stripped to expose the bare glass, typically 15 mm for single fibers, which allows proper insertion into cleavers or connectors. These lengths can vary depending on the connector manufacturer and cable type, so it is recommended to consult the strip template or datasheet provided by the connector supplier.

Best Practices

Progressive Stripping: Remove layers one at a time—jacket first, then aramid yarn, then buffer—to prevent fiber damage. Use Proper Tools: Fiber strippers, cleavers, and inspection microscopes ensure clean cuts and prevent scratches or nicks that could weaken the fiber. Cleanliness: Always clean the stripped fiber with alcohol wipes to remove debris before termination.

Safety: Wear safety glasses and handle fiber scraps carefully to avoid injury.

Summary

The exact stripping length depends on the cable construction and connector type, but a general guideline is: Outer jacket: 50–60 mmAramid yarn: slightly shorter than jacketFiber buffer: 15 mm Always verify with the connector manufacturer's strip chart to ensure optimal performance and avoid costly connector failures.
