Simple Optimization Method for Nonlinear Compensation by Filtered Backpropagation-based Equalization Utilizing Intra-stage Dispersion

We propose a simple optimization method based on the relation between the filter configuration and the dispersion compensated at each stage in order to maximize filtered backpropagation performance. We validate our method with the transmission of 127-Gb/s PM-QPSK signal over all SMF 2400 km line in...

Description
Summary:We propose a simple optimization method based on the relation between the filter configuration and the dispersion compensated at each stage in order to maximize filtered backpropagation performance. We validate our method with the transmission of 127-Gb/s PM-QPSK signal over all SMF 2400 km line in nonlinear regime.
