Stripping a 4-core optical fiber cable involves carefully removing the outer jacket, aramid fibers, and buffer coatings in stages to expose the individual fibers without causing damage.

Tools and Safety

• Kevlar scissors for cutting strength members (aramid fibers)
• Fiber optic strippers with multiple grooves for different buffer sizes
• Alcohol wipes or cleaning solution for cleaning fibers
• Safety glasses to protect eyes from fiber shards
• Clean workspace free of dust and debris

Step-by-Step Process

1. Cut the Cable Use kevlar scissors to cut the cable to the desired length. This allows easier handling and preparation for splicing or termination .
2. Remove the Outer Jacket
   • Use a fiber optic cable stripper to remove approximately 2 inches (50 mm) of the outer jacket.
   • Select the largest groove on the stripper and gently cut the jacket without nicking the fibers underneath .
3. Trim Aramid Fibers
   • Cut the exposed aramid yarn close to the jacket end using kevlar scissors.
   • Wind the fibers into a bundle to make them easier to handle and prevent interference with the fiber stripping .
4. Strip the Fiber Buffers
   • For each fiber, strip the 900-micron buffer first, then the 250-micron coating if present.
   • Use the appropriate groove on the fiber stripper and remove the coating in small steps (about 6–8 mm at a time) to reduce stress on the fiber.
   • Hold the stripper at a 45-degree angle to minimize the risk of cracking or breaking the fiber .
5. Clean the Fibers
   • Use alcohol wipes or a microfiber cloth to remove any debris or residue from the stripped fiber ends.
   • Ensure the fiber is clean and smooth before cleaving or terminating .
6. Inspect and Prepare for Termination
   • Use a fiber optic cleaver to create a clean, perpendicular end face.
   • Inspect the cleaved fiber with a microscope or visual fault locator to ensure there are no defects .

Best Practices

• Strip each layer progressively; do not attempt to remove all layers at once .
• Maintain sharp tools and replace worn blades to prevent fiber damage .
• Dispose of fiber scraps safely in a designated container to avoid injury .
• Work slowly and carefully, especially when handling multiple fibers in a 4-core cable . By following these steps and using the proper tools, you can safely strip a 4-core optical fiber cable, preparing it for splicing or connectorization while minimizing the risk of fiber damage and ensuring optimal signal performance .
