What cuts optical cables

Fiber optic cables require specialized tools such as fiber optic cleavers, cable cutters, Kevlar scissors, and fiber optic strippers to ensure precise, safe cuts.

Key Tools for Cutting Fiber Optic Cables

Fiber Optic Cleaver: This is the primary tool for cutting the glass fiber itself. It creates a clean, perpendicular cleave, which is essential for low-loss splicing and proper termination of the fiber . Cable Cutters: Used to cut through the outer jacket and strength members (like Kevlar) of the cable. These cutters must be operated carefully to avoid crushing or damaging the inner fibers . Kevlar Scissors: Many fiber optic cables contain Kevlar strands for strength. Kevlar scissors are specifically designed to cut these strands cleanly without dulling quickly . Fiber Optic Strippers: These tools remove the protective coatings and buffer layers from the fiber without damaging the delicate glass core. They are essential for preparing the fiber for splicing or termination . Utility Knife or Razor Blade: Sometimes used to score the outer jacket, but only by experienced technicians, as improper use can damage the fiber .

Safety Considerations

• Eye Protection: Always wear safety goggles to prevent injury from microscopic glass shards .
• Hand Protection: Gloves should be worn to avoid cuts from glass fibers .
• Proper Disposal: Fiber scraps are sharp and hazardous; they must be discarded in designated containers .

Cutting Procedure Overview

1. Use a cable cutter to gently score and remove the outer jacket.
2. Strip the buffer coating with a fiber optic stripper.
3. Cleave the exposed fiber with a fiber optic cleaver to ensure a smooth, perpendicular cut.
4. Cut any Kevlar strands with Kevlar scissors if present . Using these specialized tools ensures that the fiber optic cable maintains its integrity, minimizes signal loss, and reduces the risk of injury during handling.
