One possible module includes a first MPO connector and a second MPO connector exposed, and a plurality of LC connectors, the plurality of LC connectors arranged into a first row and a second row. A plurality of fibers is routed between one of the first and second MPO connectors and a different one of the plurality of LC connectors. The plurality of LC connectors in the first row and the second row are grouped into N groups with M connectors in each group corresponding to M/2 channels included in each group and including a fiber pair. The M connectors of each group are disposed across the first and second rows.
