VFL-100

Visual Fault Locator(Fiber Checker)

The VFL-100 Visual Fault Locator is a handy tool designed for checking the defects of a fiber cable. It emits a visible 650 nm wavelength red laser light through fiber optic cables, then if there are breaks or defects in the fiber will refract the light, creating a bright glow around the faulty area. The universal connector can be used for all the most widespread fiber interfaces, such as ST / SC / FC connectors. The universal connector can be used for all the most widespread fiber interfaces, such as ST / SC / FC connectors. It is suitable to test both Single-mode and Multimode cables.

With an optional 2.5 mm to 1.25 mm optional Adapter, you can quickly test a 1.25 mm diameter fiber LC or MU connector.
