How to fuse an 8-core optical cable to the panel

Fusing an 8-core optical cable to a panel involves carefully stripping, cleaning, cleaving, aligning, and splicing each fiber, followed by protecting the splices and organizing them in the panel.Step 1: Prepare the Cable

• Strip the outer jacket of the 8-core cable using a cable stripper, exposing about 50–100 cm of the inner fibers while avoiding damage to the cores .
• Remove the aramid yarn and inner coatings with a fiber optic stripper, leaving 3–5 cm of bare fiber .
• Clean each fiber with a lint-free cloth and alcohol to remove debris and coating residues .

Step 2: Install Protection Sleeves

• Slide a fiber protection sleeve onto each fiber before cleaving. This protects the bare fiber after splicing .
• Ensure the sleeve is threaded before preparing the fiber end face to avoid contamination.

Step 3: Cleave the Fibers

• Use a fiber cleaver to cut each fiber end at a precise 90-degree angle .
• Proper cleaving ensures smooth, flat surfaces for optimal fusion and minimal signal loss.

Step 4: Fusion Splicing

• Place the fibers in the fusion splicer clamps, aligning the cores using the splicer's imaging system .
• The splicer generates an electric arc to melt and fuse the fiber ends together, creating a permanent, low-loss connection .
• Repeat this process for all 8 cores individually, ensuring each splice is properly aligned and fused.

Step 5: Protect the Splices

• Slide the protection sleeve over the fused joint and shrink it using a heat source or splicer's built-in heater .
• This prevents mechanical damage and maintains tensile strength.

Step 6: Terminate in the Panel

• Organize the spliced fibers neatly in the panel, routing them into the designated slots or holders.
• Ensure strain relief is applied to prevent bending or pulling on the fibers.
• Label each fiber according to its core number for easy identification and maintenance.

Step 7: Test the Splices

• Use an optical time-domain reflectometer (OTDR) or power meter to check for insertion loss and continuity .
• Verify that all 8 cores are transmitting signals correctly before closing the panel. By following these steps, you ensure reliable, low-loss connections for your 8-core optical cable, maintaining network performance and durability.
