A communications network has a plurality of nodes interconnected by an optical transmission medium. The transmission medium is capable of a carrying a plurality of wavelengths organized into bands. A filter at each node for drops a band associated therewith and passively forwards other bands through the transmission medium. A device is provided at each node for adding a band to the transmission medium. Communication can be established directly between a pair of nodes in the network sharing a common band without the active intervention of any intervening node. This allows the network to be protocol independent. Also, the low losses incurred by the passive filters permit relatively long path lengths without optical amplification.

Réseau de communication comprenant un certain nombre de noeuds interconnectés par un support de transmission optique. Le support de transmission est capable d'acheminer un certain nombre de longueurs d'onde organisées en bandes. Un filtre à chaque noeud supprime une bande qui lui est associée et transmet passivement toutes les autres bandes sur le support de transmission. Un dispositif présent à chaque noeud permet d'insérer une bande au support de transmission. La communication peut être établie directement entre une paire de noeuds du réseau partageant une bande commune sans intervention active d'un noeud quelconque. Le réseau peut ainsi être indépendant du protocole. En outre, la faible atténuation au niveau des filtres passifs permet l'exploitation de trajets relativement longs, sans amplification optique.
