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.
We present a fast, accurate and highly parallel-processed simulation method for BER assessments of nonlinear DWDM systems based on the time-varying NLIN model with estimation errors below 0.1 dBQ and speedup factors reaching over one thousand.
