“…G OOD channel models are key to establish the mathematical framework for a better understanding of nonlinear phenomena and to effectively design fibre-optic communication systems [1]. The nonlinear Schrödinger equation (NLSE), which mathematically describes the propagation of signals in an optical fibre, is the origin for the derivation of most analytical models of nonlinear interference (NLI).…”

Communication using the optical fibre channel can be challenging due to nonlinear effects that arise in the optical propagation. These effects represent physical processes that originate from light propagation in optical fibres. To obtain fundamental understandings of these processes, mathematical models are typically used. These models are based on approximations of the nonlinear Schrödinger equation, the differential equation that governs the propagation in an optical fibre. All available models in the literature are restricted to certain regimes of operation. Here, we present an approximate model for the nonlinear optical fibre channel in the weak-dispersion regime, in a noiseless scenario. The approximation is obtained by applying regular perturbation theory on the group-velocity dispersion parameter of the nonlinear Schrödinger equation. The proposed model is compared with three other models using the normalized square deviation metric and shown to be significantly more accurate for links with high nonlinearities and weak dispersion.

“…These models lead to semi-analytical solutions of the NLIN and in some contexts, they offer an acceptable alternative to SSFTM simulations. While the EGN model provides a very good estimate of the NLIN variance, it does not account for the correlation properties of the NLIN and for this reason, it is primarily used for assessing the performance of systems in which adaptive equalization is absent [25][26][27]. The time varying ISI model, on the other hand, accounts for temporal correlation properties of the NLIN and therefore it is suitable for addressing scenarios including fast adaptive nonlinear equalization [27][28].…”

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.
