Abstract
A method of adjusting power for a WDM optical transmission system comprising emitter means, an optical transmission line, and receiver means, the method being characterized in that for each wavelength channel, the power emitted for said channel by the emitter means is adjusted as a function of the optical powers received for said channel at a plurality of points distributed along the transmission line.

A method of adjusting power for a WDM optical transmission system comprising emitter means, an optical transmission line, and receiver means, the method being characterized in that for each wavelength channel, the power emitted for said channel by the emitter means is adjusted as a function of the optical powers received for said channel at a plurality of points distributed along the transmission line.
A method according to any preceding claim, characterized in that for each channel, a reference power is continuously determined as a function of the optical powers received for said channel at a plurality of points distributed along the transmission line, said reference power being the power that ought to be received for said channel at one of the points along the transmission line, and the emitter means are controlled so as to servo-control the power at said point on said reference power.
An optical transmission system, in particular using RZ type pulses, the system being characterized in that it includes means for implementing a method according to any preceding claim.
