The AF-OS405 (635nm) visible laser cable fault locator allows the operator to find faults in fiber optic cables, even in the OTDR dead zone, optimizing splices and tracing fibers. By injecting a bright red visible light in the fiber, locations of losses such as breaks, bends, or bad connectors can be detected visually, even through the typical yellow or orange jacket used on most single fiber cables. Light generated by these units will escape from sharp bends and breaks in jacketed or bare fibers, as well as poorly mated connectors. Fibers can be traced as far as 4 km (2.5 mi.) using this instrument. The AF-OS405 uses a visible diode laser in the compact case for pocket size convenience.
Other applications include identifying connectors in patch panels and fibers during splicing operations. It is also a useful tool for continuity end-to-end checks. The unit comes in a choice of three connector options ST, FC or SC.
