How to splice a 24-core ribbon optical cable

Splicing a 24-core ribbon optical cable involves carefully splitting the ribbon into manageable subunits, preparing the fibers, and performing fusion splicing for a low-loss, permanent connection.Tools and Materials NeededFusion splicer compatible with ribbon fibersFiber cleaverRibbon splitter (optional, e.g., Fitel S233)Core tube entry tool for accessing the fiber ribbonsCleaning supplies (isopropyl alcohol, lint-free wipes)Splice tray and protective sleevesCable ties and tape for organizing ribbonsStep-by-Step Procedure1. Access the Fiber Ribbons Use a core tube entry tool to open the cable's core tube and expose the 24-fiber ribbon. Ensure the ribbons are clean and free of debris before proceeding (OFS IP-045, IP-057) . 2. Split the Ribbon (if necessary) For mass fusion splicing, it is often easier to split the 24-fiber ribbon into two 12-fiber subunits. This allows standard 12-fiber fusion splicers to be used. A ribbon splitter or careful manual separation can achieve this, ensuring fibers remain aligned and untangled . 3. Prepare the FibersStrip the coating from each fiber carefully.Clean the bare fibers with isopropyl alcohol.Use a precision cleaver to cut the fiber ends squarely, which is critical for low-loss splicing . 4. Organize the Ribbons Arrange the ribbons in the correct order, alternating top and bottom layers if needed, and secure them with tape or cable ties to maintain alignment during splicing . 5. Fusion SplicingPlace the prepared fibers into the fusion splicer.Align the fibers using the splicer's automated system.Perform the fusion splice, which melts the fiber ends together to create a permanent, low-loss joint.Repeat for all fibers in the ribbon or subunit . 6. Protect the SplicesPlace each fused fiber into a protective sleeve.Organize the spliced ribbons neatly in a splice tray to prevent bending or stress.Secure the tray inside the enclosure or closure . 7. Testing and Verification After splicing, test each fiber for continuity and signal loss using an optical time-domain reflectometer (OTDR) or power meter to ensure proper performance.Best PracticesAlways handle fibers with care to avoid microbends or scratches.Maintain a clean work environment to prevent contamination.Follow manufacturer guidelines for splicer settings and ribbon handling.Label fibers and ribbons clearly to avoid misrouting. By following these steps, a 24-core ribbon optical cable can be spliced efficiently, ensuring minimal signal loss and reliable long-term performance .
