A wavelength division multiplex (WDM) optical network comprises a ring configuration of optical fiber links (4a-4f) connecting a plurality of nodes (2a-2f) and add (8) and drop (10) filters at each node (2a-2f) connected in series within the ring. One or more of said (8, 10) filters are arranged to add or drop at least two selected adjacent wavelength channels (.lambda.N, .lambda.M) of the WDM optical signal whilst allowing the remainder of the channels within the WDM signal to pass substantially unattenuated. The wavelength channels of each node are selected such as to maximise the number of adjacent wavelength channels at each node.

La présente invention concerne un réseau optique à multiplexage par répartition en longueur d'onde (MRL), qui comprend un agencement en anneau de liaisons (4a-4f) de fibre optique reliant une pluralité de noeuds (2a-2f) et des filtres à insertion (8) et à extraction (10) placés au niveau de chaque noeud (2a- 2f) et connectés en série dans cet anneau. Un ou plusieurs de ces filtres (8, 10) sont agencés de façon à insérer ou à extraire aux moins deux canaux (.lambda.N, .lambda.M) de longueurs d'ondes contiguës sélectionnés du signal optique MRL, et ces filtres laissent néanmoins le canal restant du signal MRL passer sans affaiblissement sensible. Les canaux de longueur d'onde de chaque noeud sont sélectionnés de façon à maximiser le nombre de canaux de longueurs d'ondes contiguës au niveau de chaque noeud.
