From which end should the optical cable be laid

Optical fiber cable laying should begin from the end of the cable that is on top of the reel after flipping it, ensuring proper handling and minimal twisting.Recommended Procedure1. Cable Reel Preparation Before installation, the cable reel should be inspected for damage, and the ends of the cable must be sealed to prevent moisture intrusion. The reel should be placed on a flat, firm surface to avoid shifting or snagging during deployment . 2. Identifying the Pulling End The cable is typically coiled in a figure-8 pattern on the reel. After laying the cable in this pattern, the reel is flipped so that the end to be pulled next is on top. This ensures that the cable unrolls smoothly without twisting or kinking . 3. Handling During PullingUse swivels to prevent cable twist accumulation.Maintain the minimum bend radius specified for the cable to avoid core deformation.Pull the cable slowly and steadily, avoiding excessive tension beyond the maximum rated pulling force . 4. Environmental and Safety ConsiderationsEnsure the route is clear of sharp objects, uneven terrain, or obstacles that could damage the cable.Use cable lubricant if necessary to reduce friction in ducts.Follow all local codes and safety measures, including proper signaling and authorization for work in public areas . 5. Cable Reserves and Splicing Leave sufficient cable reserves in manholes or handholes in a figure-8 or circular pattern to facilitate splicing and future maintenance . By starting from the top end of the flipped reel, installers minimize mechanical stress, prevent twisting, and maintain the integrity of the optical fibers throughout the installation process .
