Use precision fiber strippers, thermal or automated tools, and progressive layer removal to strip optical cables quickly without damaging the fiber.

Key Principles for Safe and Efficient Stripping

1. Progressive Layer Stripping Optical cables have multiple layers: outer jacket, strength members (e.g., aramid yarn), buffer coating, and the acrylate coating protecting the glass fiber. Each layer should be stripped individually rather than all at once to avoid accidental nicks or scratches on the fiber core, which can lead to cracks or signal loss over time .
2. Use Professional-Grade Strippers
   • Mechanical Strippers: Tools like FOS03 or CFS-2 hold the fiber in a slot and remove coatings precisely. They are ideal for 125µm or 250µm fibers and allow quick, accurate stripping without damaging the glass .
   • Thermal Strippers: These use heat to soften the coating, allowing it to be removed gently. Adjustable temperature and timing ensure the fiber is not stressed or scratched .
   • Automated Strippers: Devices like AFL Precision Strip are battery-powered and can strip coatings with minimal force, speeding up the process while maintaining high-quality results .
3. Maintain Tools and Technique Sharp, well-maintained blades are essential. Dull tools increase the risk of nicks. Always replace worn tools and follow manufacturer guidelines for blade depth and stripping length .
4. Testing for Damage After stripping, perform a 45-degree bend test on the fiber. If the fiber breaks at the stripped area, it indicates a nick or scratch. This allows early detection and re-stripping before deployment, preventing costly failures .
5. Ergonomics and Field Efficiency Handheld, ergonomic strippers reduce fatigue and improve speed. Battery-powered or palm-sized tools are ideal for fieldwork, allowing rapid, precise stripping with minimal effort .

Recommended Workflow

1. Strip the outer jacket first.
2. Remove strength members like aramid yarn carefully.
3. Strip the buffer coating using a precision or thermal stripper.
4. Inspect the fiber for nicks or scratches.
5. Perform a bend test if necessary.
6. Proceed to splicing or connectorization. By combining progressive stripping, professional tools, and careful inspection, you can achieve fast, reliable fiber stripping without compromising the integrity of the optical cable .
