How to strip the fiber optic cable bundle tube

Stripping an optical fiber cable bundle tube requires carefully removing the outer jacket, aramid yarn, and buffer layers in stages to avoid damaging the fiber.

Step-by-Step Process

1. Prepare the Cable and Tools Gather a fiber stripper, kevlar scissors, and lint-free wipes with alcohol for cleaning. Ensure the fiber stripper has grooves matching the fiber buffer diameters (e.g., 900 µm and 250 µm) and that blades are sharp to prevent nicks in the fiber . 2. Cut the Cable Use kevlar scissors to cut the cable to the desired length. If practicing, you can splice the pieces later . 3. Strip the Outer Jacket

• Measure and mark the length to strip.
• Use the largest groove on the fiber stripper to gently cut the outer jacket.
• Pull off the jacket carefully, avoiding damage to the underlying aramid yarn .
• For armored outdoor cables, use a knife to cut the armor and ripcords, then pull the jacket off in pieces . 4. Trim Aramid Yarn
• Cut the exposed aramid fibers close to the jacket end using kevlar scissors.
• Wind the fibers into a bundle to make handling easier . 5. Strip the Buffer Layers
• Strip the 900 µm buffer first in small increments (~6–8 mm at a time) using the appropriate groove on the fiber stripper.
• Then strip the 250 µm buffer in similar small steps.
• Hold the stripper at a 45-degree angle to reduce stress and prevent fiber breakage . 6. Clean the Fiber
• Wipe the stripped fiber with a lint-free cloth and alcohol to remove debris.
• Ensure the fiber is free of scratches or nicks before connectorization or splicing . 7. Safety and Maintenance Tips
• Always take small cuts; never try to remove too much buffer at once.
• Maintain sharp stripper blades to prevent accidental fiber damage.
• Dispose of fiber scraps safely in a marked container to avoid injury . By following these steps, you can successfully strip an optical fiber cable bundle tube without damaging the fiber, preparing it for splicing, testing, or connectorization.
