ABSTRACT:
An optical fiber multiplexer having a fixed plate and a rotating plate. A plurality of fiber-optic channels are coupled to the fixed plate in a circumferential arrangement. One fiber-optic channel is coupled to the rotating plate. Each fiber-optic channel may include one or more separate optical fibers. A servo motor rotates the rotating plate. Switching between channels occurs by rotating the rotating plate and aligning the optical fibers on the fixed plate and the rotating plate. Lens-to-lens coupling is used to transmit optical signals between the rotating and fixed plates. An adjustment device, such as a gimbal mount, may be used to adjust the horizontal and vertical axial alignment of the optical fibers coupled to the fixed plate so that optimum light signal transmission can occur. A control unit controls the operation of the servo motor.
