Universal Virtual Lab for Fast and Accurate Performance Assessments in Nonlinear DWDM Systems with Digital Subcarrier Multiplexing

An extended Universal Virtual Lab method is presented for performance assessments of nonlinear DWDM links using 800 Gb/s digital subcarrier multiplexed channels, while accounting for NLIN correlation properties, Tx\Rx imperfections and adaptive equalization algorithms. We report accuracy errors below 0.08 dBQ and an estimated speed up factor of 5150 with respect to split-step simulations, for a 6.2 THz DWDM system.
