A METHOD FOR CONVEYING MANAGEMENT INFORMATION IN WDM SYSTEMS

摘要

Management signal are superimposed on the wavelength division multiplexing (WDM) signals in mutually distinguishable state and transmitted as a common optical signal. A detector (18) converts the tapped fraction of the optical signal into an electrical signal. A receiver (19) recovers the management signals from the electrical signal and transmits the management signals to a management unit (16). - Independent claims are included for the following: - (1) WDM system; and - (2) pluggable WDM wavelength converter.
