Abstract: An apparatus and method for optimizing dynamically the performance of an optical network, said apparatus comprising at least one learning engine adapted to update a learning model in response to network metrics of said optical network collected during operation of said optical network, wherein the updated learning model is used to generate channel rank information for network channels; and a recommendation engine adapted to change a network channel throughput, a signal path and/or a spectral location of at least one network channel based on the channel rank information generated by the learning model of said learning engine.

Abstract: A system for proactive traffic restoration in a network includes at least one forecasting engine that models and forecasts traffic patterns of at least one traffic channel along a signal path of the network to provide forecast traffic quality metrics, y. The system further includes at least one time-to-failure, TTF, analyzer that calculates a time-to-failure, TTF, forecast for the traffic channel based on the forecast traffic quality metrics, y. The calculated time-to-failure, TTF, forecast is evaluated to trigger a proactive network traffic restoration.

Abstract: An electro-optical assembly comprises a substrate having a support-surface, and a photonic integrated circuit (PIC) mounted with a contact surface on the support-surface. The (PIC) comprises an integrated optical waveguide structure defining at least two waveguide end faces, at an edge surface of the PIC, perpendicular to its contact surface, and forming optical ports. An optical coupling device, mounted with a contact surface on the support-surface, optically connects at least two optical fibers to the PIC and comprises an optical waveguide structure-defining at least two front waveguide end faces provided at a front edge surface thereof, perpendicular to its contact surface. The number of front waveguide end faces corresponds to the number of the waveguide end faces. The optical coupling device is positionable during an active positioning process to align the respective waveguide end faces. A method of manufacturing such an electro-optical assembly is also provided.
