Abstract
This paper investigates the impact of fiber nonlinear crosstalk on ultra-dense 32x16QAM-WDM with coherent detection employing Volterra series. The method is validated using Error Vector Magnitude measures against Split-Step Fourier simulations. The XPM crosstalk contribution is derived and compared to FWM and the overall system performance.
