6354 Series Optical Visual Fault Locator


The KI 6354 visual fault locator is a small, high quality and very low skill fiber cable tester. It has only one button, and an operating range of a few km.

Visible light is injected into the fiber under test, and can be seen from a fiber end, or through most 3 mm cable types at a break or loss point.

Unusually, this pen meets Class 1 safety standards (IEC IEC60825 2011) for total emitted power when no fiber is connected, so does not need any special safety eye safety precautions under any condition.
