Single mode Fiber Optic Test Equipment Visual Fault Locator VFL to Check Fibers

Fiber Optic Test Equipment Visual Fault Locator VFL to Check Fibers

General information

The Visual Fault Locator launches 650nm visible laser light into the fiber.

When the light encounters a break or sharp bend, it scatters, and the scattered light can be observed emerging from the cable. The Visual Fault Locator can locate breaks in short patch cords, which an OTDR cannot detect due to their operating dead zone. A fault locator is also much cheaper than an OTDR.

The Pen-type Visual Fault Locator can be operated in either continuous wave mode (CW mode) or in pulsed mode. Pulsed mode aids in locating faults under high ambient light conditions and improve battery life. It also could be used in checking connector quality. Often a connector may appears to be perfect. But inside the connector ferrule itself, poor gluing or dirty may create a microbend in the fiber. This microbend will produce excess insertion losses or return losses, and may result in premature failure of the connector. As the visual light launches through the fiber, it emerges from the connector in question, one can readily see

the distortion as a series of rings superimposed on a normal output. Bending or twisting the fiber may affect the overall intensity pattern, but not the ring pattern itself.
