Highly efficient pocket-size visual fault locator—the ideal complementary tool for any fiber-testing technician.

The FLS-140 is the easiest way to identify optical fibers from end to end and locate polished connector endfaces. 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.

Compact design

With a pocket-size pen-style design, this visual fault locator can easily be carried anywhere. Thanks to its anodized aluminum casing, this long-lasting and lightweight tool is the complementary tool of choice for any fiber-testing field technician.

Cost effective

The FLS-140’s extremely high efficiency guarantees prolonged operation with two standard AAA alkaline batteries, typically providing 40 hours of uninterrupted operation.

Priced to accommodate the tightest budgets, the FLS-140 is a truly affordable way to locate faults in OTDR dead zones. Its effectiveness justifies purchasing one for just about every fiber technician.
