How to sheath ribbon optical cables

Sheathing ribbon optical cables involves carefully removing the outer jacket and armor (if present) to expose the fiber ribbons, using specialized tools and safety precautions.Safety PrecautionsAlways wear safety glasses to protect your eyes from fiber shards and chemicals ( ).Use gloves when handling sharp tools, steel armor, or fiberglass rovings ( ).Avoid bending the cable beyond its minimum bend radius to prevent fiber damage ( ).Never look directly into fiber ends connected to a laser source ( ).Tools and MaterialsCable strippers (e.g., Ripley RCS-114 or RCS-158)Utility knife or hook bladeNeedle-nose pliersDiagonal cutter pliersMarker or tape for measuringProtective gloves and eyewearStep-by-Step Sheath Removal1. Measure and MarkDetermine the length of cable to be stripped based on your application (e.g., 8 feet for splicing) ( ).Mark the cable at the starting point and at the end of the section to be removed.2. Ring Cut the JacketUse a cable stripper to make a ring cut at the marked points.For armored cables, make a second ring cut closer to the cable end ( ).3. Remove the Outer JacketShave or slit the jacket between the ring cuts using a utility knife or hook blade.For armored cables, peel back the steel armor after cutting the steel wires and opening a window in the armor ( ).Use pliers to remove the remaining jacket and armor carefully.4. Expose Ripcords and Inner JacketPull the ripcords to separate the jacket from the inner core ( ).Trim water-blocking tape if present.Mark the inner jacket for the length to be removed and slit it to expose the fiber ribbons.5. Handle Fiber RibbonsCarefully slide out the central buffer tube or inner core to expose the ribbon fibers ( ).Avoid excessive pulling, bending, or crushing of the fibers ( ).Tips for Armored CablesUse a cable slitting tool to remove the outer jacket and armor without damaging the inner fibers ( ).Rotate the tool 180° and repeat the slit if necessary.Leave enough steel wire for grounding or pulling eye attachment if required ( ).SummarySheathing ribbon optical cables requires careful measurement, precise cutting, and proper use of tools to safely expose the fiber ribbons. Following safety precautions and manufacturer guidelines ensures the fibers remain intact and ready for splicing or termination ( ).
