After fusion splicing, optical fibers should be carefully placed into splice trays, secured with protective sleeves, and organized within the ODF to ensure low-loss, safe, and durable connections.

Step 1: Protect the Fusion Splice

Once the fibers are fused, slide a heat-shrink splice sleeve over the splice point and shrink it using a heat source or the splicer's built-in heater. This protects the splice from mechanical stress and environmental factors, preventing microbends or breakage during handling and reassembly .

Step 2: Place Fibers in Splice Trays

• Open the splice tray in the ODF.
• Carefully lay the spliced fibers into the tray's routing channels, following the tray's bend radius guidelines (typically >30 mm) to avoid stress on the fiber .
• Use the tray's fiber clips or holders to secure the fibers, ensuring the splice sleeve sits in the designated splice holder to prevent movement .

Step 3: Organize and Route Fibers

• Route the fibers neatly along the tray's channels, avoiding sharp bends or crossing fibers.
• Maintain minimum bend radius for both the incoming and outgoing fibers to prevent attenuation or breakage.
• If multiple fibers are spliced, organize them in layers or loops according to the tray design, keeping fibers separated to simplify future maintenance .

Step 4: Close and Secure the Splice Tray

• Once all fibers are properly routed and secured, close the splice tray cover.
• Ensure the tray is locked or latched to prevent accidental opening.
• Place the tray back into the ODF rack, aligning it with the designated slot and securing it with screws or clips as required .

Step 5: Test and Verify

• After reassembly, perform optical testing using an OTDR or power meter to verify splice integrity and ensure no additional loss occurred during handling .
• Label the fibers and trays clearly for future identification and maintenance.

Best Practices

• Always handle fibers with care, avoiding tension or contact with sharp edges.
• Keep the workspace clean and free of dust or debris to prevent contamination of splice points .
• Follow manufacturer guidelines for splice trays and ODF installation to maintain warranty and performance standards. By following these steps, your fusion-spliced fibers will be securely reassembled in the ODF, maintaining optimal performance and protecting the delicate splices from mechanical or environmental damage .
