How to cold press a fiber optic terminal box

Cold pressing a fiber optic terminal box involves using mechanical fast connectors to join fibers without epoxy or polishing, ensuring secure and efficient connections.

Preparation

Select the Installation Location: Choose a flat, accessible wall or rack space for the terminal box, ensuring it meets network requirements and allows easy maintenance. Gather Tools and Materials: You will need a fiber stripping tool, fiber cleaver, optical power meter, visual fault locator, alcohol swabs, fast connectors, and cable ties. Inspect the Box and Accessories: Check the fiber optic terminal box for defects and ensure all mounting screws, splice trays, and protective tubes are available.

Installation Steps

Mount the Terminal Box: Secure the box using expansion screws or appropriate fasteners. Ensure it is stable and level. Prepare the Fiber Cable: Strip the outer and inner jackets of the fiber cable carefully, clean the fiber, and remove any filling compound.

Wrap insulation tape around the stripped area to protect the fiber. Insert and Fix the Fiber: Feed the fiber through the entry ports of the box and fix it on the fiber fixing board. Use fiber protection tubes to prevent bending or breakage.

Cold Press Connection: Strip the fiber to expose the bare core. Cleave the fiber using a calibrated fiber cleaver to create a smooth end face. Insert the fiber into the fast connector's mechanical splice, aligning it precisely with the connector's alignment mechanism.

Secure the connector in the terminal box adapter and coil any excess fiber neatly in the splice tray.

Testing and Verification

Inspect the Connection: Use a visual fault locator to check for visible faults and ensure proper alignment. Measure Signal Quality: Use an optical power meter to verify that the optical signal is stable and within acceptable loss limits. Secure and Organize: Use cable ties and trays to manage fibers, maintaining the minimum bend radius and preventing entanglement.

Maintenance Tips

Regularly inspect the terminal box for dust, damage, or loose connections. Clean connectors and adapters with dedicated fiber cleaning tools to maintain signal integrity. Ensure fibers are not sharply bent or stressed during operation or maintenance.

By following these steps, you can cold press a fiber optic terminal box safely and efficiently, achieving reliable fiber connections without epoxy or polishing, while maintaining optimal network performance.
