CROSS-PHASE MODULATION IMPACT ON COHERENT OPTICAL 16 QAM-WDM TRANSMISSION SYSTEMS
01 March 2011
This article investigates the impact of fiber nonlinearcrosstalk on ultradense 32x_x0001_ 16 QAM-WDM with coherent detection using Volterra series. The method is validated using Error Vector Magnitude measures against Split-Step Fourier simulations. The crossphase modulation crosstalk contribution is derived and compared to four-wave mixing and the overall system performance.
