摘要

After an introduction to the nonlinear fiber transmission and an optimal channel equalization scheme, recently proposed analytical step-size selection and scaling rules was verified to achieve comparable global simulation accuracy for split-step Fourier (SSF) simulations of optical pulse propagation through fiber with low simulation accuracy. Its application to digital post-compensation and its computational performance was systematically studied for return to zero (RZ) and carrier suppressed return to zero (CSRZ) modulation formats with different inline dispersion map degrees.
