  • Channel mask definition for monitoring wavelength division multiplexing transmission systems
    Patent number: 6751413
    Abstract: Multiple signals are monitored, for example, by an instrument used for monitoring wavelength division multiplexing (WDM) transmission systems. For each monitored frequency channel, an active mask is initialized. The active mask includes an operating window defined by a minimum frequency, a maximum frequency, a minimum amplitude and a maximum amplitude. Each signal is monitored to determine when the signal strays outside the operating window. An alarm is generated when the signal strays outside the operating window.
    Type: Grant
