  • Method and system for signaling defects in a network element with optical fabric
    Patent number: 10447420
    Abstract: Embodiments include methods and apparatuses for providing at least one signaling indication of a super-channel by a power controller in a Wavelength Division Multiplexing (WDM) system. The power controller may receive a service provisioning and a lock state from a network management entity. The power controller may receive, from an optical fabric unit, a fabric state that indicates whether a pass-band of the super-channel is provisioned. The power controller may receive the power level of the super-channel from a power monitoring unit. Based on the power level and attenuation level of the super-channel, the power controller may determine a ramp state that indicates whether the power level reached to a predetermined power. The power controller may determine an alarm state based on the power level. The power controller may determine the signaling indication based on the service provisioning, lock, fabric, ramp, and alarm states.
