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

1. 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 .
2. 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 .
3. 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

1. Mount the Terminal Box: Secure the box using expansion screws or appropriate fasteners. Ensure it is stable and level .
2. 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 .
3. 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 .
4. 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

1. Inspect the Connection: Use a visual fault locator to check for visible faults and ensure proper alignment .
2. Measure Signal Quality: Use an optical power meter to verify that the optical signal is stable and within acceptable loss limits .
3. 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.
