Two white tubes inside the 8-core optical cable

The two white tubes inside an 8-core optical cable are connected by carefully stripping, cleaning, and fusion splicing the individual fibers within each tube.Step-by-Step Process1. Prepare the Cable and Tubes Begin by stripping about 1 meter of the outer jacket to expose the loose tubes. Carefully separate the two white tubes you want to connect, avoiding any twisting or damage to the fibers inside. Use a loose tube tool to open the tubes and remove the protective gel or coating if present . 2. Strip and Clean the Fibers Inside each white tube, strip the individual fiber coatings using fiber stripping pliers. Clean the bare fibers thoroughly with alcohol wipes to remove any residue or gel . This ensures a clean surface for splicing. 3. Protect the Fibers Slide heat-shrinkable tubes over the fibers before splicing. These will protect the fibers after the splice is complete and prevent breakage . 4. Fusion Splicing Turn on the fusion splicer and allow it to warm up for at least 15 minutes. Insert the prepared fibers into the splicer, aligning them precisely. Select the appropriate fusion program based on the fiber type (single-mode or multimode). The splicer will generate an electric arc to weld the fiber cores together, producing a low-loss, permanent connection . 5. Protect the Splice After splicing, slide the heat-shrinkable tube over the splice and shrink it using a heat source. This provides mechanical protection and maintains alignment . 6. Organize and Secure Place the spliced fibers back into the splice tray or closure, ensuring the tubes are laid in order to avoid twisting. Secure the cable and tubes to prevent movement that could stress the splices .Tips and Best PracticesAlways clean tools and fibers before splicing to minimize attenuation .Use a fusion splicer for permanent connections; mechanical splicing is only recommended for temporary or quick fixes .Follow the TIA-598-C color code to correctly identify fibers within multi-tube cables, ensuring proper matching of fibers .Handle fibers gently; they are extremely fragile once stripped . By following these steps, the two white tubes in your 8-core optical cable can be connected efficiently, ensuring minimal signal loss and long-term reliability.
