A method for the management of a one-directional optical management loop with optical frequency multiplexing. This method is characterized chiefly in that the central station (T) instructs a secondary station (Si) that it designates to tune its reception to a determined wavelength (.lambda.j), on the basis of a message broadcast permanently to all the secondary stations (S1-Sn) on all the channels of the frequency multiplex. This method can be applied to any type of telecommunications network.

Method for the management of wavelength-division-multiplexed optical

In a telecommunications network organized in wavelength-division-multiplexed optical loops, each loop has tunable reception means tuned as a function of the density of the network traffic, thus being capable of being reconfigured as a function of requirements. The disclosed system can be applied to public, private and data communication networks.
