Enabling S-C-L-Band Systems with Standard C-Band Modulator and Coherent Receiver using Nonlinear Predistortion

We experimentally demonstrate S-band reception of 64-GBd PDM-64/32-QAM using standard C-band components. Operation below SD-FEC is enabled by nonlinear transmitter pre-distortion based on coherent system identification supporting up to 150 nm bandwidth in the S-C-L-band.
