A METHOD FOR CONVEYING MANAGEMENT INFORMATION

摘要

The invention relates to a method for conveying management information in a WDM system from a number of wavelength converters (10a) to a central management unit (16), wherein a management information signal is superimpose d on the WDM signal from the respective wavelength converter (10a). A fraction of the optical signal in the common optical transmission line (13a) is tappe d off to a detector (18) and the different management information signals are recovered by a receiver unit (19) which is connected to the detector (18). T he invention also relates to a WDM system and a pluggable WDM wavelength converter.
