Nous proposons et démontrons pour la première fois à notre connaissance, une architecture de circuit de commutation optique dotée de la fonction "Bridge and Switch", conforme à la recommandation ITUT-T G. 841 Annexe A pour les multiplexeurs optiques Add-Drop (ADM) dans WDM quatre -réseaux en anneaux de fibres. Cette fonction permet aux ADM optiques de passer automatiquement de l'état de commutation à leur état de veille juste après la reprise après panne, ce qui est indispensable pour gérer le trafic supplémentaire afin d'améliorer l'efficacité du fonctionnement du réseau. Nous avons développé les nœuds ADM optiques utilisant le circuit de commutation optique proposé pour chaque longueur d'onde, des réseaux de guides d'ondes en réseau (AWG) et des amplificateurs à fibre dopée à l'Er. Dans la démonstration, les caractéristiques de transmission des nœuds ADM optiques en cascade sans répéteurs régénératifs ont été vérifiées dans un premier temps. Nous avons confirmé la protection en anneau et la séquence de commutation de protection automatique (APS) qui inclut la réversion automatique dans les nœuds ADM optiques avec les circuits de commutation optique proposés.

Abstract: We propose and demonstrate for the first time in our knowledge, an optical switch circuit architecture furnishing with the "Bridge and Switch" function, conforming to ITUT-T Recommendation G. 841 Annex A for optical Add-Drop Multiplexers (ADMs) in WDM four-fiber ring networks. This function enables optical ADMs to revert automatically from the switching state to their idle state just after the recovery of failure, that is indispensable for the extra traffic accommodation to enhance efficiency of the network operation. We have developed the optical ADM nodes employing the proposed optical switch circuit for each wavelength, arrayed-waveguide gratings (AWGs) and Er-doped fiber amplifiers. In the demonstration, transmission characteristics of the cascaded optical ADM nodes without regenerative repeaters have been verified at first. We have confirmed the ring protection and the automatic protection switching (APS) sequence which includes the automatic reversion in the optical ADM nodes with proposed optical switch circuits.
