Evaluation of an Autonomous Digital Pre-distortion Scheme for Optical Multiband Systems

We demonstrate a DSP scheme that autonomously adapts the design of Volterra and memory polynomial digital pre-distortion filters in S+C+L-band transmission. We validate it with a DP-32QAM signal at 64 GBd over 40-km of SSMF.
