Carefully strip the outer sheath, insert the fiber cable into the junction box opening, and secure it without bending or stressing the fibers.

Step-by-Step Guide

1. Prepare the Junction Box Mount the round junction box securely on the wall or designated surface. Use a spirit level to ensure it is straight, drill the necessary holes, and attach the box with screws and dowels if required . 2. Prepare the Fiber Optic Cable Carefully remove the outer sheath of the fiber optic cable to expose the inner fibers. Avoid pulling or twisting the fibers themselves; only handle the cable's strength members (Kevlar or fiberglass rods) to prevent breakage . Ensure the cable length is sufficient to reach the junction box comfortably. 3. Insert the Cable Feed the prepared cable through the designated opening or cable gland in the junction box. Do not push the fiber; gently pull it into place to maintain the minimum bend radius and prevent kinking . Make sure the cable is seated properly in the box without sharp bends. 4. Secure the Cable Use the provided clamps or cable holders inside the junction box to fix the cable in place. Tighten screws carefully to avoid crushing the cable. If the box has a threaded adapter or gland, ensure the cable passes through it and is sealed properly . 5. Connect and Splice Fibers Follow the manufacturer's instructions to splice or connect the fibers inside the junction box. Ensure all connections are tight and properly aligned to maintain signal integrity . 6. Test the Connection After installation, test the fiber optic line using a fiber optic tester to confirm proper signal transmission. Contact your Internet provider if necessary to verify functionality . 7. Maintenance Tips Keep the junction box clean and free of dust. Avoid bending or crushing the cable, and periodically check connections for tightness . Proper care ensures long-term performance and reliability. By following these steps carefully, you can safely insert a fiber optic cable into a round junction box while protecting the delicate fibers and ensuring a stable connection.
