ABSTRACT:
A battery powered portable test instrument for detecting whether light is propagating in an optical fiber has a jaw into which the fiber is placed, the jaw being closable to press a section of the fiber into a bend having predetermined radius of curvature. If light is propagating through the fiber it is scattered and detected in a detection circuit. If the detected light is greater than the predetermined threshold, an indicator circuit is energized.
