Abstract :
We evaluated the averaged Q-factor for optical signals distorted by chromatic dispersion in a transmission fiber. This letter confirms that our method has sensitivity to bit error rate degradation due to both the signal-to-noise ratio degradation of pulse distorted signals and pulse distortion itself. It also explains how fault detection in an optical network system can be done with this method.
