The 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 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.
