ABSTRACT:
An apparatus and method for selectively blocking optical light signals provided from a plurality of input fiber optical strands with an optical switch. An input fiber termination port is provided for coupling the plurality of input fiber optical strands to the optical switch. The input fiber termination port has a center and a plurality of rows of openings. Each of the rows of openings is aligned radially with respect to the center and has a plurality openings for receiving ends of the input fiber optical strands. An output fiber termination port is provided for coupling a plurality of output fiber optical strands to the optical switch. An interior optical path transmission region is bounded on a first end by the input fiber termination port and on a second end by the output fiber termination port. A movable light blocking structure is positioned within the interior optical path transmission region for selectively blocking the optical signals from passing between input fiber optical strands positioned along at least one of the rows of openings in the input fiber termination port and corresponding output fiber optical strands positioned in the output fiber termination port. An electromechanical actuator drives the movable light blocking structure in step-wise angular increments, wherein the step-wise angular increments correspond to an angular distance between adjacent rows of openings in the input fiber termination port.
