Stripping Techniques for 48-Core Optical Cables

Stripping a 48-core optical cable requires careful, progressive removal of the outer jacket, strength members, and individual fiber buffers using specialized tools to avoid fiber damage.

Preparation and Safety

Before starting, ensure a clean, well-lit workspace free from dust and debris. Wear safety glasses to protect your eyes from fiber shards, and have alcohol wipes or cleaning solution ready for cleaning stripped fibers . Lay out all tools within reach, including fiber strippers, cleavers, and inspection microscopes.

Step-by-Step Stripping Process

1. Strip the Outer Jacket
   • Use a fiber optic jacket stripper suitable for the cable diameter.
   • Carefully remove the outer sheath without nicking the aramid yarn or inner fibers.
   • For multi-layer cables, strip each layer progressively: jacket first, then aramid yarn, then buffer tubes .
2. Remove Strength Members
   • Cut or pull out aramid yarn or fiberglass strength members carefully. These provide tensile strength but must not damage the fibers underneath .
3. Expose Individual Fibers
   • Strip the buffer coating from each fiber using a precision fiber buffer stripper matched to the fiber diameter.
   • Use color-coded blades or guides to ensure consistent stripping without microfractures .
4. Clean and Inspect Fibers
   • Wipe each stripped fiber with alcohol wipes to remove debris.
   • Use a fiber inspection microscope or visual fault locator (VFL) to check for nicks, scratches, or irregular cleaves .
5. Cleaving for Termination
   • Use a fiber optic cleaver to create a clean, perpendicular end face.
   • Adjust cleaver settings according to fiber type and desired cleave length. Repeat for all 48 fibers individually .

Best Practices

• Progressive stripping: Never attempt to strip all layers at once; each layer requires careful attention.
• Tool maintenance: Keep blades sharp and clean to prevent accidental fiber damage .
• Consistent technique: Maintain uniform stripping lengths and cleave quality across all fibers to ensure reliable terminations.
• Safe disposal: Collect and safely dispose of fiber scraps to prevent injury .

Recommended Tools

• Fiber optic jacket stripper for multi-core cables
• Precision buffer strippers with fiber guides
• Fiber cleaver for clean end faces
• Inspection microscope or VFL
• Alcohol wipes and lint-free cloths
• Safety glasses and gloves By following these steps and using the proper tools, you can safely strip a 48-core optical cable while maintaining fiber integrity and preparing it for high-quality termination or splicing.
