Description:Fiber Optic (VFL) Visual Fault Locator for 1.25mm LC Connectors; 8km
Item #:MT-7509

The MT-7509 fiber optic visual fault locator is an indispensable tool for quickly identifying bending losses and breaks in optical fibers. if a fiber is bent too tightly, red laser light will be seen escaping through the jacket. Likewise, if a fiber is broken, escaping light will be visible where the break is located.

Ceramic connectors are easily tested using the MT-7509 fiber optic visual fault locator. A fiber broken inside, or past, the ferrule will cause it to glow. If the whole connector glows, it is definetely defective. If the end face polish of the connector is bad, light will be reflected internally. This will also make the ferrule glow when the MT-7509 is used.
