A method of and system for estimating the bit error rate of a channel in an optical communication system includes a method of and system for measuring the in-band cross-talk of the channel in a wavelength division multiplexed system. A single channel is selected from the plurality of channels in the optical communication system. The signal in this single channel is passed to a digital signal processor proportional to the time rate of change of a phase of an optical source generating the signal. The digital signal processor converts the filtered signal into the frequency domain, and a spectrum analyzer determines the features of the in-band cross-talk from the signal in the frequency domain. The features of the in-band cross-talk may be combined with other measured noise features, such as the power spectral density, to estimate BER.

L'invention concerne un procédé et un système d'estimation du taux d'erreur binaire d'un canal d'un système de communication optique, qui consistent à mesurer l'intermodulation intrabande du canal dans un système multiplexé en longueur d'onde. Un seul canal est sélectionné de l'ensemble des canaux dans le système de communication optique. Le signal dans ce canal unique est transféré à un processeur de signaux numériques proportionnellement au taux de changement temporel d'une phase d'une source optique générant le signal. Le processeur de signaux numériques transforme les signaux filtrés en domaine fréquence, et un analyseur de spectre détermine les caractéristiques de l'intermodulation intrabande provenant du signal dans le domaine fréquence. Les caractéristiques de l'intermodulation intrabande peuvent être associées à d'autres caractéristiques de bruit mesurées, telles que la densité du spectre de puissance, afin d'estimer le taux d'erreur binaire (TEB).
