Abstract :
Different approaches to split-step-Fourier-method (SSFM) applied to simulation of signal propagation in wavelength-division-multiplexed (WDM) links are considered in this paper. We propose novel simulation method, which contains two stages: step size optimization is carried out in the initial stage, using two recently proposed methods: local-error method and pre-simulation with signal spectrum averaging; in the second stage conventional SSFM is used, applying optimal steps obtained in the initial stage. Overall time savings reach 50%, depending of simulated system scenario. We called this novel procedure pre-simulated local error S-SSFM (PsLE S-SSFM).
