Fiber stripping lengths for splice closures typically range from 1 meter of bare fiber for loose tube cables to 38–120 mm for protective coating removal, depending on closure type and manufacturer instructions.

Typical Fiber Stripping Guidelines

• Loose Tube Cables: For standard loose tube cables, the buffer tubes are usually extended from the cable entry to the splice tray, and approximately 1 meter of bare fiber on each side of the splice is prepared for splicing and storage in the tray .
• Protective Coating Removal: The protective coating of individual fibers is stripped to lengths ranging from 38 mm to 120 mm, depending on the closure design and tray configuration . This allows the fiber to be spliced and neatly coiled inside the splice tray without stress or pinching.
• Ribbon or Matrix Fibers: Special care is required for ribbon fibers, which may only bend in one direction. Stripping lengths are determined by the closure manufacturer to ensure proper routing and minimal stress on the fibers .

Manufacturer and Installation Considerations

• Follow Manufacturer Instructions: Each splice closure may have specific requirements for stripping lengths, buffer tube preparation, and securing fibers to the tray .
• Sectional Stripping: If it is difficult to remove the protective coating in one step, fibers should be stripped section by section to avoid breakage .
• Fiber Management: After stripping, fibers should be carefully arranged in the splice tray to prevent stress, pinching, or bending beyond the minimum bend radius. Covers and stacked trays can pinch fibers if not properly managed .

Summary

While there is no single universal standard, common practice is to strip fibers to lengths that allow safe splicing and storage, typically 1 meter of bare fiber for loose tube cables and 38–120 mm for protective coating removal, with exact lengths determined by the closure type and manufacturer guidance . Proper adherence ensures long-term reliability and minimizes the risk of fiber damage during installation or maintenance.
