Distributed 1-Tb/s all-optical aggregation capacity in 125-GHz optical bandwidth by frequency conversion in fiber
We demonstrate the spatially distributed aggregation of four 31.1-GBd PDM-32QAM sub-carriers into a 1-Tb/s net data rate superchannel occupying only 125-GHz optical bandwidth, and its subsequent transmission over 160-km SSMF with broadband reception in a single coherent receiver.
