“…Simulation of large channel-count systems are extremely demanding in terms of computational resources and often require unacceptably long computation time when relying on the conventional split-step Fourier-transform method (SSFTM) [18]. A GPU based implementation of the SSFTM has been reported in [19] but even then, the runtime was only decreased by a factor of 40 for a simulation bandwidth of 4 THz. Since the complexity grows at least as a fourth power of the DWDM bandwidth [18], SSFTM becomes impractical for ultra-wideband systems operating beyond the C-band and alternative solutions must be proposed while ensuring a careful trade-off between accuracy and computational runtime.…”

Abstract-We introduce the concept of the universal virtual lab, an extension to the virtual lab platform of [30], enabling a fast and accurate simulation of wideband nonlinear DWDM systems. The universal virtual lab is compliant with non-ideal transmitter and receiver architectures, distributed optical filters in the optical link, inter-channel stimulated Raman scattering, and it provides accurate performance predictions even when adaptive equalization methods are applied. In comparison with the conventional full-bandwidth split step Fourier transform method, we show with different test scenarios that the universal virtual lab provides accuracy errors below 0.1 dBQ and 0.09 bit/4D-symb in Q-factor and GMI assessments respectively, with runtime speedup factors exceeding 1000. We also report performance assessments in an ultra-wideband (11 THz) C+L system and discuss equalization gain under different compensation scenarios. The estimated speedup factor with respect to the fullbandwidth split step Fourier transform method is assessed to be greater than 35,000.

With the extension of the spectral exploitation of optical fibers beyond the Cband, accurate modeling and simulation of nonlinear interference (NLI) generation is of the utmost performance. Models and numerical simulation tools rely on the widely used Manakov equation (ME): however, this approach when considering also the effect of polarization mode dispersion (PMD) is formally valid only over a narrow optical bandwidth. In order to analyze the range of validity of the ME and its applicability to future wide-band systems, we present numerical simulations, showing the interplay between NLI generation and PMD over long dispersion-uncompensated optical links, using coherent polarization division multiplexing (PDM) quadrature amplitude modulation (QAM) formats. Using a Monte-Carlo analysis of different PMD realizations based on the coupled nonlinear Schrödinger equations, we show that PMD has a negligible effect on NLI generation, independently from the total system bandwidth. Based on this, we give strong numerical evidence that the ME can be safely used to estimate NLI generation well beyond its bandwidth of validity that is limited to the PMD coherence bandwidth.

“…To validate this hypothesis, we set up a numerical simulation using the Split-Step Fourier method [37] to measure the correlation of NLPN without ASE noise nor laser phase noise. To perform a fair comparison with the experimental results, simulations have been carried out with the same number of WDM channels (31 at 16 GBaud with 25 GHz spacing).…”
