Abstract
Digital Backward Propagation (DBP) algorithm for mitigating fiber dispersion and non-linearities based on modified non-iterative symmetric split-step Fourier method (M-SSFM) is implemented and numerically evaluated. The algorithm is modified by shifting the calculation point of non-linear operator (r) together with the optimization of dispersion (D) and non-linear coefficient (γ) to get the optimum system performance. DBP is evaluated for 10x10Gbit/s wavelength division multiplexed (WDM) system (a total transmission capacity of 100Gbit/s) with RZ-DQPSK encoded signals over a transmission length of 1600km standard single mode fiber (SMF) with no in-line optical dispersion compensation. Furthermore, we quantify the impact of optical add-drop multiplexers (OADMs) in the transmission link. Modification of DBP parameters and bandwidth of optical filters associated with OADMs give significant improvement in the system performance.
