An optical node includes a reconfigurable optical add drop multiplexer (ROADM) core configured to transmit optical signals of multiple wavelengths to and receive optical signals of multiple wavelengths from another optical node. The ROADM core is also configured to add optical signals thereto and to drop optical signals therefrom. The node also includes two different types of add-on devices, each connected to the ROADM core device and configured to process optical signals of multiple wavelengths. As a result, a multifunctional and reconfigurable optical node can be provided.
Un noeud optique comprend un noyau de multiplexeur optique reconfigurable à insertion/extraction (ROADM) configuré pour transmettre des signaux optiques de plusieurs longueurs d'onde et pour recevoir des signaux optiques de plusieurs longueurs d'onde en provenance d'un autre noeud optique. Le noyau ROADM est également configuré pour ajouter des signaux optiques à ce dernier et pour éliminer des signaux optiques de ce dernier. Le noeud comprend également deux types différents de dispositifs d'ajout, qui sont chacun connectés au dispositif de noyau ROADM et configurés pour traiter les signaux optiques de plusieurs longueurs d'onde. On obtient ainsi un noeud optique multifonctionnel et reconfigurable.
