Reconfigurable ring transmission network with multiplexing in wavelength for semi-permanent links, the network including at least one ring (10) comprising nodes (12) and at least one optical fiber (18, 20) passing through the nodes, and each site (13) in the network comprises transmission-reception means (EN, ES, RN, RS) for one or more wavelengths and each node comprises optical add-drop means (IN, IS, XN, XS) for this wavelength and optical switching means (CN, CS) to connect these means to the transmission-reception means, the network used for optical telecommunications.
