Visual Fault Locators GAO’s fiber visual fault locators are handheld devices used in the field of fiber optics to locate faults or breaks in optical fiber. GAO’s fiber visual fault locators are used for troubleshooting and maintenance tasks in fiber optic networks. They emit a bright visible laser light into the fiber optic cable, allowing technicians to easily locate faults by visually observing the light leakage or breakage. GAO’s fiber visual fault locators are composed of a laser diode, power control, connector adapter, battery, switch/button, indicator lights, housing or enclosure, and output port. The other common names for visual fault locators are fiber optic fault finders, fiber fault detectors, optical cable fault locators, visual fiber testers, visual cable break detectors, visual fiber break locators, optical fiber break detectors, visual fault detectors, light source fault locators, fiber break pinpointers, fiber fault tracers, cable break testers, visual break locators, fiber break testers, and fiber optic cable fault tracers.
