Abstract (en)
[origin: WO0103338A1] An optical transmission system having a dense wavelength division multiplexer (DWDM). A disturbance is inserted into the output of each wavelength transmitter. A feedback control system for stabilizing the wavelength of each transmitter employs a method for ananalyzing the output of a device having wavelength dependent transmission for signatures of the disturbances.
