Abstract :
A methodology is presented for estimating the bandwidth of the low-pass filter (LPF) used in the LPF assisted digital back propagation algorithm for mitigating the effects of intra-channel fiber nonlinearities. The usefulness of the methodology is demonstrated for an experimental 112 Gb/s dual-polarization 16-QAM system.
