Abstract
This ring network for wavelength-multiplexed information transmission. comprises two optical fibres (F1, F2) passing through nodes (N1 to N4) of the network and traversed in the opposite direction by informations, electronic add-drop multiplexers (ME1 to ME4) or ADM, each ADM supplying information to other ADM's, of the network at given wavelengths and optical add-drop multiplexers (M01 to M04) or OADM, each OADM adding to the fibres the informations from the associated ADM and extracting from said fibres the informations intended for said ADM. Application to optical telecommunications.
