A small plastic molded 50-fiber connector has been developed for high-count optical subscriber cables. The connetor ferrule has a two-dimensional fiber arrangement constructed by five layered 10-fiber ribbons. The ferrules are precisely aligned by alignment pins and a guide sleeve. The fabricated 50-fiber connector, which has a small sectional area of 4 mm6 mm, exhibits an average loss of 0.23 dB for graded-index optical fibers. Connection loss chang is small after over 1000 times reconnection.
