Abstract :
This paper presents the chromatic dispersion dependence of the averaged Q-factor method based on an evaluation of an asynchronous amplitude histogram. We analyze nonreturn-to-zero optical signals using a numerical simulation based on several parameters for signal quality monitoring. The results are compared with the optical signal-to-noise ratio dependence of the method and the possibility of distinguishing the origins of the bit-error-rate distortion is discussed.
