VIAVI Visual Fault Locators

Visual Fault Locators

Optical Fiber Damage/Break Locator

VIAVI Solutions offers two unique versions of the VFL that are economically priced and ergonomically designed for comfortable handling and portability.
Both versions are equipped with a 2.5 mm interface and are compatible with connectors such as SC, ST, and FC, while the included 1.25 mm adapter enables connection to LC and MU connectors. The VFL emits a visible red light, making the light escaping from the damaged fiber easily visible from a distance.

The Continuous/Flash control button lets operators choose between continuous or flashing illumination.
