How to connect the small hole in the fiber optic connector closure

To connect a fiber optic cable through the small hole in a closure, properly prepare the cable, select the correct sealing rings, insert the cable, and secure it with clamps and sealing tape to ensure a stable, low-loss connection.

Step-by-Step Procedure

1. Prepare the Fiber Cable

• Remove the outer jacket, shielding, and armor to expose the loose tubes, leaving sufficient length for splicing and storage inside the closure .
• Clean the exposed fibers and strength members with a suitable cleaning solution, and abrade the outer jacket slightly to ensure proper sealing . 2. Select and Install Sealing Components
• Choose sealing rings that match the cable diameter and slide them onto the cable .
• Wrap self-adhesive sealing tape between the rings to create a tight seal that aligns with the closure entry . 3. Insert the Cable into the Small Hole
• Position the prepared cable into the designated small entry hole of the closure .
• Ensure the cable is properly aligned and that the strength members or metallic shielding are grounded if required . 4. Secure the Cable
• Use a hose clamp or the closure's built-in securing mechanism to hold the cable firmly in place .
• Tighten the clamp to prevent movement and maintain strain relief, avoiding stress on the fibers . 5. Fiber Management Inside the Closure
• Coil excess fiber neatly inside the splice tray, leaving 1.5 loops for flexibility .
• Use nylon ties to secure buffer tubes and distinguish between outgoing and customer fibers with color-coded ties . 6. Seal Unused Ports
• Any small holes or ports not in use should be sealed with plugs and additional sealing tape to maintain environmental protection . 7. Final Checks
• Verify that the fiber is not kinked or stressed, and that the closure is fully sealed .
• Clean the connector end faces before mating to minimize signal loss . By following these steps, the small hole in the fiber optic closure will be properly utilized, ensuring a secure, weatherproof, and low-loss connection for your fiber optic network.
