Fast and accurate waveform modeling of long-haul multi-channel optical fiber transmission using a hybrid model-data driven scheme. (arXiv:2201.05502v1 [eess.SP])

The modeling of optical wave propagation in optical fiber is a task of fast
and accurate solving the nonlinear Schr\"odinger equation (NLSE), and can
enable the research progress and system design of optical fiber communications,
which are the infrastructure of modern communication systems. Traditional
modeling of fiber channels using the split-step Fourier method (SSFM) has long
been regarded as challenging in long-haul wavelength division multiplexing
(WDM) optical fiber communication systems because it is extremely
time-consuming. Here we propose a linear-nonlinear …
