Abstract (en)
[origin: WO02075971A2] The invention relates to an optical transmission system in which the signals ( lambda 1, lambda 2, lambda 3, ...) are transmitted at different wavelengths between terminals (T1, T2, T3 ...) of a transmission network (IL1, IL2, IL3) and only those signals ( lambda 1, lambda 2) are regenerated whose quality parameters require regeneration. A management system, when deciding about the location of regeneration, takes the design and the properties of the transmission network including the existing regeneration possibilities and the possible routing into consideration.
