FTTH New Cable Reel Maintenance

Proper maintenance of new FTTH cable reels ensures optimal network performance, prevents damage during handling, and extends the lifespan of fiber optic infrastructure.Handling and StorageNew FTTH cable reels must be stored in a clean, dry, and temperature-controlled environment to prevent moisture ingress and physical damage . Reels should be kept upright on stable surfaces and protected from direct sunlight or extreme temperatures. When moving reels, use appropriate lifting equipment to avoid bending or crushing the cable, as excessive tension or sharp bends can degrade optical performance .Inspection Before DeploymentBefore installation, perform a visual inspection of the cable for any cuts, dents, or abrasions on the jacket. Check the integrity of the reel and end caps to ensure the cable has not been contaminated with dust or moisture . Verify that the fiber count and type match the network design specifications .Cleaning and PreparationFiber optic connectors and cable ends should be cleaned using dry, lint-free wipes or spectroscopic-grade methanol. Avoid touching the fiber ends with bare hands, and use powder-free gloves when handling optical surfaces . Ensure that dust caps remain in place until the cable is ready for splicing or termination .Installation Best PracticesDuring deployment, maintain the minimum bend radius specified by the manufacturer to prevent microbends or macrobends that can increase insertion loss . Use cable guides, rollers, and tension control devices when pulling cable from the reel to avoid kinks or excessive tension. For aerial or underground installations, coordinate with local authorities and follow safety protocols, including warning signs, traffic control, and gas detection in manholes .Testing and VerificationAfter installation, perform OTDR (Optical Time-Domain Reflectometer) testing to detect any faults, high insertion loss, or reflections along the cable . Record baseline measurements for future maintenance comparisons. For drop cables, conduct visual fault locator (VFL) tests and inspect closures for moisture or seal integrity .Preventive MaintenanceEven new cables benefit from scheduled inspections. Recommended intervals include monthly physical checks for tension or damage, quarterly OTDR scans, semi-annual insertion loss spot checks, and annual visual inspections . Maintain a log of all inspections and test results to track trends and identify potential issues early.Safety ConsiderationsAlways follow safety protocols when handling fiber optic cables, including avoiding direct eye exposure to laser light, using proper personal protective equipment, and ensuring power sources are turned off during cleaning or splicing . Proper ventilation and gas monitoring are essential for underground work . By following these guidelines, FTTH operators can ensure that new cable reels are installed safely, perform reliably, and maintain long-term network integrity.
