Title

Improving achievable information rates of 64-GBd PDM-64QAM by nonlinear transmitter predistortion

Abstract
We assess the gains in achievable information rate for 64-GBd PDM-64QAM signal transmission with Volterra-based digital predistortion of nonlinear transmitter components and show an improvement of up to 0.6 bit/4D-symbol over conventional linear predistortion.
