Abstract[English]
Reconfigurable optical add-drop multiplexers (ROADMs) are disclosed. A ROADM includes D optical inputs that receive optical signals, D first optical switching devices, each first optical switching device being associated with one of the D optical inputs, second optical switching devices associated with one of the outputs of a corresponding first optical switching device, each second optical switching device fans-out the optical signal into N multiple signals, third optical switching devices, that combine second output signals received from a corresponding M=D/N of the second optical switching devices, and combining devices that, in use, combine third output signals of N corresponding third optical switching devices and provide a set of D optical outputs of the ROADM and a controller communicably connected to the first, second, third and fourth optical switching devices to adjust a switching state thereof.[French]
Des multiplexeurs d'insertion-extraction optiques reconfigurables (ROADM) sont divulgués. Un ROADM comprend D entrées optiques qui reçoivent des signaux optiques, D premiers dispositifs de commutation optique, chaque premier dispositif de commutation optique étant associé à l'une des D entrées optiques, des deuxièmes dispositifs de commutation optique associés à l'une des sorties d'un premier dispositif de commutation optique correspondant, chaque deuxième dispositif de commutation optique extrait le signal optique en N signaux multiples, des troisièmes dispositifs de commutation optique, qui combinent des troisièmes signaux de sortie reçus en provenance d'un M = D/N correspondant des deuxièmes dispositifs de commutation optique, et des dispositifs de combinaison qui, lors de l'utilisation, combinent des troisièmes signaux de sortie de N troisièmes dispositifs de commutation optique correspondants et fournissent un ensemble de D sorties optiques du ROADM et un dispositif de commande connecté en communication aux premier, deuxième, troisième et quatrième dispositifs de commutation optique pour ajuster un état de commutation de ceux-ci.
