Abstract: Disclosed herein are methods and systems configuring a raman amplifier. One exemplary system may be provided with an optical amplifier deployed in an optical network, the optical amplifier having a plurality of raman pumps configured to obtain a desired gain profile. An actual gain profile and a raman pump configuration of each of the plurality of raman pumps may be processed by a network administration device using a first machine learning model to produce a combined optical transmission segment attribute representing attributes of an optical segment of the optical network. The combined optical transmission segment attribute and the desired gain profile may be processed with a second machine learning model to produce corrected raman pump configurations for each of the plurality of raman pumps of the raman amplifier. The corrected raman pump configurations may be used to configure each of the plurality of raman pumps of the raman amplifier.

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.

Abstract: Disclosed herein are methods and systems for configuring a raman amplifier. One exemplary system may be provided with a raman amplifier having a plurality of raman pumps and a controller, and a network administration device. The network administration device generates and deploys a first machine learning model and a second machine learning model to the controller of the raman amplifier. A desired gain profile may be automatically assessed using the first machine learning model to determine raman pump configurations for each of the plurality of raman pumps of the raman amplifier. The raman pump configurations for each of the plurality of raman pumps of the raman amplifier may be processed with the second machine learning model to produce an output gain profile. The determined raman pump configurations are deployed only if the output gain profile and the desired gain profile match to within a margin of error.
