Abstract: Described are methods and systems for predicting and generating impacted scenarios based on a defined set of attributes. The system includes one or more databases. The processors are configured to receive a set of service provider system attributes for a project, generate attribute combinations from the set of service provider system attributes using a machine learning model trained on a reference data model, wherein the reference data model includes multiple test scenarios from the one or more databases, each test scenario associated with a test scenario attribute combination, generate predicted scenarios from the attribute combinations using the machine learning model, determine impacted service provider systems based on the predicted scenarios, determine issues based on each of the predicted scenarios, and generate a complexity score based on the determined impacted service provider systems and the determined issues to determine project viability.

Abstract: A set of three gratings may be operated in a vernier loop fashion to select a particular wavelength from a wavelength division multiplexed system. As a result, an optical add/drop multiplexer may be provided that can be tuned to select a desired wavelength. In one embodiment, the tuning may be done thermo-optically.
