Abstract: A backplane connector for mating with a daughter-card connector assembly, said backplane connector having a front and rear orientation and comprising: (a) a retainer block configured for attachment to a backplane and defining a plurality of ferrule slots, each slot configured to receive a ferrule; (b) a plurality of ferrules disposed in said ferrule slots; (c) a plurality of ferrule springs to urge said plurality of ferrules forwardly; and (d) Fwafera plurality of ferrule spring retainers for retaining said ferrule springs and being mounted rearward on said retainer block, wherein each ferrule spring retainer retains springs for two or more ferrules.

Abstract: A daughter-card connector assembly comprising: (a) a housing defining a first plane configured for mounting parallel to a backplane, and a second plane for mounting parallel to a daughter card, and a plurality of parallel slots perpendicular to said first plane; and (b) one or more opto-electric cards, each of said one or more opto-electric cards disposed in one of said plurality of slots, and comprising at least, (i) a printed circuit board (PCB) defining at least a first edge and a second edge, wherein, when said opto-electric card is mounted in said slot, said first edge is parallel to said first plane and said second edge is parallel to said second plane; (ii) a blind-mate optical connector along said first edge; (iii) an electrical interface along said second edge; (iv) at least one optical component mounted on said PCB for converting between electrical and optical signals, said PCB being electrically connected to at least a portion of said electrical interface; and (v) one or more waveguides connecting
