Visible cracks, flattened jackets, sharp bends, dirty connectors, and corroded ferrules are typical indicators of cable damage. How do you test a fiber cable for faults? Use a Visual Fault Locator (VFL) for quick field checks, and an OTDR for detailed fault location and loss. Don't let cable woes ruin your streaming binge or video conference; instead, explore these six proven ways to troubleshoot and fix your optical cable issues. Before diving into solutions, it's crucial to understand what an optical cable is and how it works. Optical cables transmit data as light. Fiber damage doesn't always mean a visible break.
