Abstract :
We theoretically study optical transmission characteristics of wavelength-division multiplexed (WDM) and polarization-multiplexed (POLMUX) signals using high-order optical quadrature-amplitude-modulation (QAM) formats up to 256. Conducting intensive computer simulations on bit-error rates in WDM POLMUX QAM transmission systems, we find maximum transmission distances under the influence of nonlinear impairments.
