Viavi FFL-055 Pocket-Sized Visual Fault Locator - 5mW

Whether you're installing new fiber or troubleshooting a network issue, the VIAVI Fiber Optic Visual Fault Locator (VFL) is an essential tool for identifying problems in fiber optic cables. The high-power 5 mW red laser makes it easy to spot breaks, sharp bends, and faulty splices by emitting visible light that escapes from damaged sections of the fiber, even from a distance.

Technicians use the VFL to pinpoint damage, perform continuity tests, and identify fibers quickly and accurately. The FFL Series Visual Fault Locators are available in pocket-sized and ruggedized form factors, both featuring a universal 2.5 mm connector interface and a 1.25 mm adapter for compatibility with SC, ST, FC, LC, and MU connectors. A built-in Continuous/Flash mode switch allows for easy toggling between illumination styles depending on the application.
