Patent ID: 8184978

Claim:
A method for optical data transmission in a wavelength multiplexing system having at least two transmission channels of different wavelengths, the method comprising the steps of: determining at least one value which is a measure of a physical property of an optical data transmission path of the wavelength multiplexing system; and automatically adjusting a transmission parameter of at least one transmission channel of the transmission channels as a function of the determined at least one value so as to improve transmission quality for the at least one transmission channel; wherein the at least two transmission channels are combined by an optical multiplexer and transmitted to a receiver via the optical data transmission path and wherein each transmission channel corresponds to at least one transmission laser, at least one data source, and at least one modulator; and wherein the automatically adjusting step includes at least one of: adjusting a wavelength corresponding to a transmission laser; adjusting a data transmission rate corresponding to a data source; and adjusting a modulation format corresponding to a modulator.
