Abstract
A ganged optical switch is provided for switching a first optical fiber into and out of axial alignment with a second optical fiber. The fibers are secured to first and second carriages respectively. By relatively moving the carriages, the optical fibers can be moved into and out of axial alignment. Two test optical fibers ganged to the first and second optical fibers provide test path for transmitting an optical signal along. The fibers forming the test path are positioned at particular locations on the carriages such that when the test optical fibers are axially aligned, the first and second fibers are guaranteed to be axially aligned. An optical detector is positioned at an end of one of the test fibers and an LED is provided at an end of the other of the test fiber. An indication of alignment is provided when light from the LED is detected by the optical detector.
