ABSTRACT:
A fiber optic line simulator simulates the attenuation in a fiber optic cable with repeatable accuracy by adjusting the air spacing between the ends of two foreshortened fiber optic cables adapted to be connected to a continuity meter or other device for measuring attenuation in a fiber optic cable of extensive length. The simulator may also simulate specific fiber optic lengths for use in evaluation of optical communication systems.
