Abstract
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.
