ABSTRACT:
An optical backplane is made by making an aperture (15) at each of a plurality of output ports (13). The optical fiber (12) is adhered to the substrate such that all of the optical fiber segments of each output port traverse the aperture of that port. Next, the optical fiber segments traversing each aperture are contained between a pair of first (18, 19) optical fiber support members on opposite sides. The support members are next encapsulated in a plastic encapsulation (24), preferably by injection molding. The encapsulation, support members and substrate are cut transversely to the optical fiber segments, and the exposed ends (27) of the optical fiber segments are polished. This provides a connector for the output port to which a matching array of optical fibers (32) contained between opposite second support members can be abutted and aligned so as to transmit light from the output port the second optical fibers. The support members also contain an alignment aperture (20), and identical second optical fiber support members are made to receive alignment pins (29) adapted to be inserted into matching alignment apertures for aligning the optical fiber segments to the second optical fibers.
