Abstract: Disclosed herein are methods and systems for generating and/or obtaining at least one loading policy for a transmission line segment that is currently operating, the at least one loading policy comprising a combination of loading parameters for one or more types of loading management operations associated with the transmission line segment. At least one of the loading policies may be activated on a network element of the transmission line segment. Upon receiving a loading request to change a spectral loading pattern of the transmission line segment, current loading data of the transmission line segment and loading parameters from the activated loading policy may be obtained and used to generate a loading response. A signal containing the loading response may be sent to the network element, the signal configured to cause the network element to change the spectral loading pattern of the transmission line segment based on the loading response.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for performing asymmetric pulse-shaping filtering. In some implementations, a receiver comprises a detector circuit operable to receive optical signal data from an optical link. The receiver comprises a filter circuit, coupled to the detector circuit, operable to (i) filter the optical signal data according to an asymmetric filtering scheme and (ii) output the filtered optical signal data, wherein the asymmetric filtering scheme comprises utilizing a shaping filter with first criteria, the first criteria including one or more values greater than one or more values of second criteria utilized by a shaping filter at a transmitter, the transmitter communicating with the receiver.

Abstract: Networks and network elements having a service and power control orchestrator are disclosed, including a network element comprising a processor; a first port coupled to a first optical link carrying a first optical signal; a WSS having a multiplexer, a demultiplexer, and a control block operable to control the multiplexer/demultiplexer. The WSS operable to switch the first optical signal into a second optical signal. A second port is coupled to a second optical link, operable to carry the second optical signal, and in optical communication with the WSS. A memory stores an orchestrator application, an OTSA component, a service component, and instructions that cause the processor to: store a logical ROADM model having a connectivity matrix of the network element; receive a communication associated with the control block based on the logical ROADM model; and transmit, to the control block, a service loading sequence based on the logical ROADM model.

Abstract: An optical network and a method of use are herein disclosed. The method comprises: receiving, by a DEMUX module of a local ROADM, a request from an upstream ROADM, the upstream ROADM being upstream from the local ROADM on a fiber optic line, the local ROADM comprising the DEMUX module and first and second MUX modules, the request including first instructions to perform an operation on the local ROADM; sending, by the DEMUX module, a distributed request to the first and second MUX modules, the distributed request including second instructions to perform the operation on the first and second MUX modules; attempting, by the first and second MUX modules, to perform the operation; and sending a consolidated response to the upstream ROADM indicative of one of a success and a failure of performing the operation on the first and second MUX modules.

Abstract: An optical network and a method of use are herein disclosed. The optical network comprises a fiber optic line, two or more ROADMs, and an orchestrator comprising a processor and a non-transitory computer-readable medium storing processor-executable instructions that, when executed, cause the processor to: receive an operation to execute, the operation being a loading of a first optical service on the fiber optic line by a local ROADM; determine a status of a downstream ROADM as being available; reserve the downstream ROADM for the loading of the first optical service by preventing the downstream ROADM from loading a second optical service on the fiber optic line and disabling one or more control block of the downstream ROADM, thereby preventing the one or more control block from adjusting a configuration of the downstream ROADM; and load the first optical service on the fiber optic line.
