Simulation step-size optimization based on an analytical step-size selection rule is applied to the waveform level simulation of polarization multiplexed optical signal propagation through dispersion compensated optical fiber links over a large range of simulation accuracy level, chromatic dispersion, and differential group delay.
Extensive numerical simulation validated that the studied method is a local error method and it achieves similar local or one-step simulation error. Combining the local error and global error control, the developed simulation package can significantly speed up the time-consuming simulations which are typical in the coherent optical fiber communication system design.
