Visual Fault Locator (VFL)

A visual fault locator is a visible red laser designed to inject visible light energy into a fiber. Sharp bends, breaks, faulty connectors and other faults will “leak” red light allowing technicians to visually spot the defects.

The VFL is an ideal tool for locating a large number of defects that occur at connection points in and around fiber cabinets which are hidden in an OTDR “blind-spot” or dead-zone.

The Pocket Pal is the easiest way to identify fibers from end to end and locate polished connector endfaces. Its red laser shines through most yellow-jacketed 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-240 locates faults visually by creating a bright red glow at the exact location of the fault on singlemode or multimode fibers.

Due to its small size, lightweight and simple but proven design, the Pocket Pal can accompany you anywhere. In your pocket or belt pouch, carry your FLS-240 to the most demanding environments. To ensure ruggedness, it features rubber seals, a fully enclosed laser head and a long-lasting On/Off switch. It has been tested to provide reliable operation under intensive use and harsh conditions.
