Abstract

In an improved optical switch, light from an input optical fiber is directed to one of a plurality of output optical fibers on a selective basis. The output fibers are contained in a bundle, preferably within a removable connector, thereby easing removal and maintenance. The input fiber also preferably forms pair of a bundle within a removable connector. The means for selectively directing the light from the end of the input fiber to the end of one of a plurality of the output fibers may include a pivot upon which at least the input optical fiber is mounted, or an electro-optic Bragg cell without moving parts. One or more lenses are preferably used between the end of the input optical fiber and the ends of the output fibers to assist in directing the light. A preferred arrangement incorporates two lenses, positioned so that the end of the output fiber and the end of a selected input fiber are each located at the focal point of one of the lenses.
