Cet article propose un système d'égalisation de dispersion automatique utilisant la surveillance de la puissance d'horloge extraite afin de faciliter l'installation sur le terrain de systèmes de multiplexage temporel (TDM) à grande vitesse sur des câbles à fibres existants. Le schéma proposé ajuste la dispersion d'un égaliseur à dispersion variable de manière à maximiser le niveau de puissance d'horloge extrait. Ce schéma a une configuration simple, ne nécessite aucun canal de communication entre l'émetteur et le récepteur et est sensible à des paramètres tels que le gazouillis initial et la puissance d'entrée de la fibre. La dépendance de la puissance d'horloge sur la dispersion de la fibre est théoriquement analysée en supposant que le format de retour à zéro (RZ) est utilisé et que l'élargissement des impulsions est faible par rapport à la durée du bit. Nous montrons que la puissance d'horloge est maximisée lorsque la distorsion de la forme d'onde induite par la dispersion est minimisée. Les simulations numériques montrent que le schéma proposé est efficace avec le format sans retour à zéro (NRZ) et dans le cas où la dispersion totale optimale s'écarte de zéro en raison du gazouillis initial et/ou induit par l'auto-modulation de phase (SPM). . Le fonctionnement du système d'égalisation automatique proposé est confirmé expérimentalement dans une transmission à 20 Gbit/s utilisant à la fois les formats RZ et NRZ. De plus, une expérience de transmission à 40 Gbit/s sur 200 km de fibre à dispersion décalée (DSF) est démontrée avec succès en utilisant le schéma d'égalisation proposé.

Abstract: This paper proposes an automatic dispersion equalization system using extracted clock power monitoring in order to facilitate the field installation of high-speed time-division multiplexed (TDM) systems over existing fiber cables. The proposed scheme adjusts the dispersion of a variable-dispersion equalizer so as to maximize the extracted clock power level. This scheme has a simple configuration, needs no communication channel between the transmitter and the receiver, and is sensitive to parameters such as initial chirping and fiber input power. The clock power dependence on the fiber dispersion is theoretically analyzed assuming that the return-to-zero (RZ) format is used and that pulse broadening is small compared to the bit duration. We show that the clock power is maximized when the dispersion-induced waveform distortion is minimized. Numerical simulations show that the proposed scheme is effective with the non-return-to-zero (NRZ) format and for the case that the optimum total dispersion deviates from zero due to initial and/or self-phase modulation (SPM)-induced chirping. The operation of the proposed automatic equalization system is experimentally confirmed in 20-Gbit/s transmission using both RZ and NRZ formats. Moreover, a 40-Gbit/s transmission experiment over 200 km of dispersion-shifted fiber (DSF) is successfully demonstrated using the proposed equalization scheme.
