Abstract
An optical interface including a keyway formed in a printed circuit board and a mating portion attached to the ends of a plurality of optical fibers. Openings in a surface of the keyway communicate light from the fibers to semiconductor chips on the board by means of optical waveguides formed in the dielectric layers of the printed circuit board. The keyway accurately aligns the mating portion which aligns the ends of the fibers with the openings.
