200Gbits/s transmission over 4.4km of multimode OM2 fiber with direct detection using mode group multiplexing

We demonstrate a total of 200Gbits/s bidirectional transmission (100Gbits in each direction) over 4.4km of OM2 fibre with direct detection and a selective excitation of 4 mode groups thanks to mode group multiplexer based on Multi-Plane Light Converter
