Its red laser shines through most yellow-jacketed optical fibers to help you pinpoint breaks, bends, faulty connectors, splices and other causes of signal loss. It has a reach of up to 5 km. The convenient FLS-140 locates faults visually by creating a bright red glow at the exact location of the fault on singlemode or multimode optical fibers.
