Disclosed herein are methods and systems for correcting power excursions. One exemplary network element may be provided with a processor; a first line port; a flexible ROADM module including a wavelength selective switch, a multiplexer, and one or more control block; a second line port; and a memory storing an orchestrator application and processor-executable instructions. Responsive to receiving a first signal indicative of an impending network state change, the processor-executable instructions cause the processor to pause all power adjustments by the control block on the flexible ROADM module and save at least one power set point value for each active passband from a first optical signal multiplexed into a second optical signal; and responsive to receiving a second signal indicative of the network state change, adjust an optical power of each active passband from the first optical signal multiplexed into the second optical signal using the power set point values.

Systems and methods for correcting downstream power excursions during upstream loading operations in optical networks

Disclosed herein are methods and systems for configuring a spectral loading pattern for a transmission line segment in an optical network, the method comprising obtaining at least one loading policy, activating at least one of the at least one loading policy, receiving a plurality of requested operations, obtaining one or more static datapoint and one or more dynamic datapoint associated with the transmission line segment, obtaining loading parameters and one or more loading algorithm from the at least one activated loading policy, generating a loading response according to the one or more loading algorithm, and changing a spectral loading pattern of the transmission line segment based on the loading response. The requested operations may identify operations to be executed in either of a current cycle or one or more subsequent cycle. The loading response may identify a subset of the operations to be executed in the current cycle.

Method of transient management in optical transmission systems

Systems, methods, and devices for adding an alien or native wavelength optical signal to a fiber optic line. A portion of a spectrum of the fiber optic line corresponding to the optical signal is blocked with a wavelength selective switch (WSS). The portion of the spectrum is gradually unblocked until a power of the optical signal measured after the WSS is equal to a predetermined level. If the power and characteristics of the optical signal after the WSS satisfy one or more criteria, the portion of the spectrum is further unblocked until the power of the optical signal measured at the output is equal to an operational level.
