La diaphonie inter-canaux est l'un des facteurs limitants des systèmes optiques multicanaux. Cet article présente une analyse théorique des performances du taux d'erreur binaire (BER) des signaux de modulation par déplacement de phase en quadrature (QPSK) et de modulation d'amplitude en quadrature (QAM) influencés par plusieurs canaux de diaphonie. La distribution de champ de plusieurs canaux de diaphonie dans la carte de constellation est calculée. Le BER du signal QPSK/QAM, sur lequel la lumière de diaphonie est superposée, est ensuite évalué pour un nombre variable de canaux de diaphonie à condition que la puissance de diaphonie totale soit constante. Les résultats confirment quantitativement qu'à mesure que le nombre de canaux augmente, la dégradation du BER provoquée par la lumière diaphonique se rapproche de celle provoquée par la lumière du bruit gaussien. Il est également confirmé que les dégradations provoquées par la lumière diaphonique et la lumière gaussienne sont similaires pour les signaux QAM de modulation de haut niveau.

Abstract: Inter-channel crosstalk is one of the limiting factors in multichannel optical systems. This paper presents a theoretical analysis of the bit-error-rate (BER) performance of quadrature phase shift keying (QPSK) and quadrature amplitude modulation (QAM) signals influenced by multiple crosstalk channels. The field distribution of multiple crosstalk channels in the constellation map is calculated. The BER of the QPSK/QAM signal, onto which the crosstalk light is superimposed, is then evaluated for a varying number of crosstalk channels under the condition that the total crosstalk power is constant. The results quantitatively confirm that as the channel number increases, the BER degradation caused by crosstalk light approaches that caused by Gaussian noise light. It is also confirmed that the degradations caused by crosstalk light and Gaussian light are similar for QAM signals of high-level modulation.
