METHOD AND APPARATUS FOR RAPID RECOVERY OF OPTICAL POWER AFTER TRANSIENT EVENTS IN C+L BAND OPTICAL NETWORKS

Abstract:

An optical device having an amplifier and a controller is described. The amplifier is configured to amplify an optical signal in at least one of the C-Band or the L-Band. The controller includes a processor and a non-transitory computer readable medium. The non-transitory computer readable medium storing computer executable code that when executed by the processor causes the processor to: select a target tilt and gain setting from a plurality of target tilt and gain settings stored in the non-transitory computer readable medium based on the type of fault event message responsive to a fault event message affecting the C-band or the L-Band. The selected and pre-calculated target tilt and gain settings are applied to the amplifier.
