FIBERtest (ST-257813 and ST-257130)

The FIBERtest Compact Fiber Optic Tester is a precision calibrated hand-held optical verifier tool. For fiber optic cable installers and network troubleshooters on a budget, it is a must have. Featuring a conversion switch for automatic signal attenuation calculation, the FIBERtest makes verifying integrity of fiber optic cables virtually effortless.

This pocket sized tool sends a visible red laser light though fiber optic cables.  Breaks or faults 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 commonly used fiber interfaces.
