1. Maintain Minimum Bend Radius: Always respect the minimum bend radius of the fiber. For unarmored cables, do not bend less than 10 times the cable diameter; armored cables require at least 15 times the diameter. Individual buffer tubes and fibers should not be bent below 38 mm (1.5 inches) to avoid microbending and signal attenuation . 2. Use Splice Trays: Splice trays are designed to store coiled fibers neatly. Each fiber should be routed in the tray without crossing over other fibers, and splices should be secured in holders to prevent movement . Dome-type closures often provide more organized fiber management compared to inline closures . 3. Coil Fibers in Loops: Excess fiber should be coiled in gentle loops inside the tray. Start by wrapping the fiber at least one full turn at the bottom of the closure shell before leading it to the splice tray. Avoid tight bends and excessive tension . Use protective sleeves for single-core or ribbon fibers if required, and secure with nylon straps without over-tightening . 4. Prepare Cable Properly: Strip the cable jacket and expose the buffer tubes according to manufacturer instructions. Leave sufficient fiber length to allow coiling and splicing. Clean and abrade the fiber and strength members to ensure proper sealing and grounding . 5. Secure and Seal: After coiling, fasten fibers in the tray and secure the closure. Use sealing rings and self-adhesive tape to prevent moisture ingress. Align the closure shells and tighten bolts diagonally, then recheck after 10 minutes to ensure a proper seal . 6. Ground Metallic Components: If the cable has metallic strength members or shielding, ensure proper grounding and bonding at each end of the closure to prevent electrical hazards and maintain network integrity .
