Abstract: A fiber optic lane changer includes a first and a second connector. A plurality of lane changer transmission paths include first ends received within the first connector and second ends received within the second connector. The first ends are arranged in respective ones of a first subset of a plurality of optical interface positions in a standardized connector configuration, and the second ends are arranged in respective ones of a second subset of the plurality of positions. In certain embodiments, the plurality of lane changer transmission paths have first ends that are aligned to optically couple with respective ones of the eight outermost optical transmission paths of the first connector. At least one of the lane changer transmission paths may have a second end that is aligned to optically couple with one of the four innermost optical transmission paths of the second connector.
