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.

Abstract: A transport network, a node, and a method are disclosed. The transport network, the node, and the method detect a failure of a super channel originating from a sliceable light source that is routed through the transport network, by detecting an optical loss of signal by an optical power monitoring device, in presence or absence of an optical loss of signal of the complete band by at least one photo detector. This information is analyzed with a fault detection algorithm using a patch cable network configuration to determine a fault indication for a failure within the first node. The fault signal indicative of the fault indication is then passed to another node on the first path.

Abstract: A system and method is disclosed in which circuitry of a first controller of a first node on a first path within a transport network receives a first signal indicating a failure within the first path from a second controller. The first node is an end node of the first path. A first client signal failure clear signal is received from a second node upstream of the first node on the first path. The first client signal failure clear signal indicates that a non-restorable fault has been resolved such that the first path can be considered for carrying data traffic. The non-restorable fault is a failure at the source. Subsequent to receiving the first signal indicating the failure within the first path, a backward defect indication clear signal is transmitted to the second node, the backward defect indication clear signal indicating an absence of a failure in the first path.

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: Disclosed herein are methods and systems for computing a launch power for an optical node by collecting data for an optical network segment and inputting the collected data and first power spectral density values into a machine learning model which are used to compute a first non-linear interference value. A first generalized-optical signal-to-noise ratio value is computed using the computed first non-linear interference value and amplified spontaneous emission values. At least one second generalized-optical signal-to-noise ratio value is computed using at least one second non-linear interference value, computed using at least one second power spectral density values, and the amplified spontaneous emission values. A highest generalized-optical signal-to-noise ratio value is determined by comparing the first generalized-optical signal-to-noise ratio value and the at least one second generalized-optical signal-to-noise ratio value. A launch power is computed using the power spectral density values associated with the highest generalized-optical signal-to-noise ratio.

Abstract: Systems and methods are described in which circuitry of a first controller of a first node receives a first signal indicating an optical loss of signal within the first path. Circuitry of a second controller of the first node on the first path within a transport network generates a second signal indicating a failure within the first path. The first controller accessing a network topology database determines that restoration of the first path would be ineffective due to there being no alternate path, and signals a second node downstream in the first path with the second signal indicating the failure within the first path, and a third signal indicating that restoration of the first path would be ineffective due to there being no alternate path.

Abstract: Networks and network elements having an optical power control block, service and power control orchestrator, used to activate, deactivate and perform optical control of channels is disclosed hereby. The invention introduces the idea that, user created service would be activated or deactivated in smaller increments which would help to mitigate power transient on the transmission line. This approach of incremental activation or deactivation would help to correct against undesirable power changes on rest of the optical channels sharing the common optical path. In addition, it provides a way to monitor the health of increment under activation throughout the activation and if necessary optical power thresholds being not met, it can be rolled back. During the process of such an incremental activation or deactivation, the already activated portion of the channel would continue to be optically controlled independently.
