FLS-140
VISUAL FAULT LOCATOR (VFL)
Highly efficient pocket-size VFL—the ideal complementary tool for any fiber-testing technician.
KEY FEATURES
Bright red laser at 655 nm Pulsed and CW operation
40 hours of operation (typical) Standard AAA alkaline batteries Pocket-size pen-style design
2.5 mm universal connector
FLS-140
The FLS-140 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-140 locates faults visually by creating a bright red glow at the exact location of the fault on singlemode or multimode fibers.
Compact design
With a pocket-size pen-style design, this VFL can easily be carried anywhere. Thanks to its anodized aluminium 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.
* Typical length of continuous fiber at which end-to-end identification is possible, depending on fiber attenuation. VFL depends on ambient light conditions at test site.
