Visual Fault Locator

A Visual Fault Locator (VFL) is a tool used by technicians to identify faults or breaks in fiber optic cables. It emits a red, laser-like light into the fiber, allowing the technician to visually detect issues such as bends, cracks, or disconnections by observing where the light escapes or drops off. This helps ensure the fiber optic network is functioning correctly and makes troubleshooting quicker and more accurate without needing complex equipment or extensive disassembly.
