How to install the ODF protection tube after fiber optic cable fusion

After fusion splicing, the ODF protection tube is installed by securing the spliced fiber in a heat-shrinkable tube, fixing it on the fusion splice disc, and routing it safely within the ODF.

Step-by-Step Installation

1. Prepare the Fiber and Cable Lead the optical cable to the ODF's cable fixing plate. Cut approximately 1 meter of the cable end, then strip about 1500 mm of the outer jacket. Insert the ground wire barbed end into the stripping position and wrap it tightly with film to ensure proper contact with the armored steel tape. Cut the metal reinforced core to about 85 mm and fix it on the steel wire fixing seat, securing the cable with a hose clamp for stability . 2. Replace the Bundle Tube with PVC Protective Hose After stripping, slide a PVC protective hose over the fiber bundle. Place the pre-disc on the take-up area and introduce the fusion splice disc. Fix the PVC protective hose onto the fusion splice disc using a cable tie to prevent movement . 3. Prepare and Route the Fiber Pigtail Take a fiber pigtail of appropriate length (usually 2 meters) and label both ends. Fix one end to the adapter on the 6-port adapter mounting plate and route the other end to the fusion splice disc. Secure the pigtail with a cable tie on the disc to maintain proper alignment . 4. Fusion Splicing and Protection Move the rear box cover with the fusion splice plate outside the ODF for splicing. After fusion, slide a heat-shrinkable tube over the splice point and place it in the heat-shrink tube holder on the fusion splice disc. Apply heat to shrink the tube, ensuring the splice is fully protected . 5. Final Securing and Routing Reattach the rear cover to the ODF body. Straighten and fix the optical fiber along the designated routing paths. If using a 19-inch fiber distribution frame, introduce the PVC hose directly into the cable tie plate at the rear of the box and secure it similarly . 6. Inspection and Testing Visually inspect the splices and protective tubes for proper alignment and damage. Perform continuity testing using a light source or power meter to verify signal integrity. Ensure all fibers are neatly organized and labeled for future maintenance . By following these steps, the ODF protection tube will securely safeguard the fusion splices, maintain fiber integrity, and ensure a clean, organized installation within the ODF.
