Abstract :
Based on measurements, we derive a linear and nonlinear pre-distortion tailored to the components of an optical transmitter and investigate their performance in simulations and experiments. Significant performance improvements are demonstrated for higher-order modulation formats such as 64- and 128-QAM.
