ABSTRACT:
Two fixed input optical fibers may be aligned with two movable output optical fibers. The two output fibers are moved by exchanging the positions so that either output fiber may be optically aligned with either input fiber. In another optical switch either one of two movable fibers may be optically aligned with either one of two fixed fibers by rotating the movable member. In yet another optical switch a movable fiber may be aligned with one of a number of fixed optical fibers by rotating the movable member using a stepping motor. The angular positions of the fixed fibers are such that the input fiber is optically aligned with any one of the fibers by rotating the input fiber by a number of steps of the stepping motor.
