Abstract

Input optical fibers 1 can be switched into alignment with output optical fibers 2 without placing any physical stress on the fibers or depending on electronic circuits. Interconnecting fibers are contained in a movable element (rotary or translational) with a fixed pattern which permits switching an input to one of N possible outputs. Three typical configurations are shown. In the first example (Fig. 1), input optical fibers 1 are stationary and in contact with the input face 4. Output fibers 2 are also stationary and in contact with the output face 5. The feedthrough switch, a cylinder 6 in this example, is physically rotated to establish various alignments between fibers. In this example, two channels (7 and 8) are shown, but any number of channels and fibers per channel could be used. In Fig.
