We briefly introduce a concept for linear and nonlinear digital pre-distortion (DPD) of high-speed optical transmitters. As an extension to previous results, we investigate the impact of the DPD schemes on a wavelength-division multiplexing (WDM) transmission of 32 GBd polarization division multiplexed (PDM) M-ary quadrature amplitude modulated (M-QAM) signals. The investigated formats range from 32- to 128-QAM
