FLS-190 - High-power visual fault locator (VFL)

This high-power pocket-sized VFL is an essential tool for any technician testing fiber over long distances.

FLS-190 - High-power visual fault locator (VFL)

The FLS-190 is the easiest way to identify fibers from end to end, and to locate polished connector endfaces. Its red laser shines through most jacketed fibers to help you pinpoint breaks, bends, faulty connectors, splices and other causes of signal loss. With its 5mW output, it has a reach of up to 12 km (typically, depending on fiber attenuation and on ambient light conditions).

The FLS‑190 pinpoints faults visually by creating a bright red glow at the exact location of the fault on singlemode or multimode fibers. It can also be used to identify the port of a fiber in a patch panel.
