A full‐duplex data link at 10 Gbit/s per channel (two upstream and two downstream) between two compact bidirectional optical sub‐assemblies is presented. Each sub‐assembly is based on the authors' optoelectronic ferrule and carries both laser diodes and photodiodes while maintaining a compact form factor of less than 20 mm 3 . The authors use plastic optical fibres with 50 µm graded‐index cores and thin 125 µm claddings bundled in a four‐channel ribbon but split the ribbon in order to reach both laser diodes and photodiodes within the optoelectronic ferrule, hence directly butt‐coupling each channel with its own optical fibre. This method keeps both assembly form factor and complexity at a minimum and performance high. Eventually error‐free signal transmission at 10 Gbit/s per channel over 5 m with 0.67 unit intervals eye opening is confirmed.
