Cold splicing installation of Type 86 fiber optic panel

Cold splicing in a Type 86 fiber optic panel involves mechanically joining fibers using a cold connector, ensuring proper alignment, minimal signal loss, and secure mechanical fixation.

Step-by-Step Cold Splicing Procedure

1. Prepare the Cold Connector Install the cold connector into the Type 86 panel, ensuring the snap rings on both sides are properly positioned and the middle slot is ready to receive the fibers .
2. Strip and Clean the Fiber Ends Strip approximately 3 cm of the fiber coating from each end. Clean the exposed fiber with alcohol to remove any debris or contaminants .
3. Cut the Fiber to Length Using a precision fiber cleaver, cut each stripped fiber to about 1.4 cm. Ensure the cut is clean and perpendicular to the fiber axis to minimize insertion loss .
4. Insert Fibers into the Cold Connector Insert one fiber end into the cold connector, then repeat for the other fiber. Make sure the bare fibers are properly seated in the snap ring in the middle of the connector .
5. Secure the Snap Rings Push the snap rings on both sides tightly to lock the fibers in place. This ensures mechanical stability and proper optical alignment .
6. Test the Connection After installation, test the splice for optical continuity and insertion loss. Properly installed cold splices typically have slightly higher loss than fusion splices (around 0.3 dB), but are suitable for temporary or quick installations .

Best Practices

• Cleanliness is Critical: Always ensure fibers and connectors are free from dust or oil, as contamination can significantly increase splice loss .
• Proper Alignment: Use the snap ring and alignment features of the cold connector to maintain precise fiber alignment. Misalignment can cause back reflection and signal degradation .
• Minimize Handling Stress: Avoid bending or stressing the fibers near the splice to prevent microbends or breakage .
• Documentation: Label each splice in the Type 86 panel for easy identification and future maintenance .

Advantages of Cold Splicing

• Quick Installation: Does not require expensive fusion splicing equipment.
• Reversible: Fibers can be removed or repositioned if needed.
• Cost-Effective for Short Runs: Ideal for temporary connections or field repairs .

Considerations

While cold splicing is convenient, it generally has higher insertion loss and lower long-term durability compared to fusion splicing. For permanent, high-bandwidth installations, fusion splicing is preferred, but cold splicing is effective for rapid deployment, testing, or temporary setups in Type 86 panels . By following these steps and best practices, a Type 86 fiber optic panel can be efficiently populated with cold splices, ensuring reliable optical performance and mechanical stability.
