Abstract

The printed circuit board assembly includes a printed circuit board having an interior portion upon which a flexible optical circuit is mounted and edge portions surrounding the interior portion. The flexible optical circuit includes a pair of at least partially flexible sheets and a number of optical fibers sandwiched between the flexible sheets. The first ends of the optical fibers extend toward an edge portion of the printed circuit board. In order to conserve space along the edge of the printed circuit board while providing interconnections for each of the optical fibers, a multifiber connector can be mounted upon the respective first ends of a predetermined number of optical fibers. Connectors, such as single fiber connectors, are also mounted to the second ends of the optical fibers. While a number of single fiber connectors occupy more space than a multifiber connector, the single fiber connectors mounted upon the second ends of the optical fibers lie within the less populated interior portion of the printed circuit board, thereby permitting more efficient utilization of the edge portion of the printed circuit board.
