Abstract

L'invention concerne un réseau en anneau optique unidirectionnel comportant plusieurs noeuds de réseau (NA, NB, ...) à chacun desquels est affectée une voie de transmission (μA) ayant une bande de transmission utilisée une seule fois. On configure le réseau à l'aide de filtres de réception (54) commutables ou réglables.
