Patent ID: 11038615

Abstract:
A method of managing an optical communications network comprising a plurality of nodes interconnected by optical sections. The method comprises: identifying one or more pairs of adjacent DL-equipped nodes at which dummy light (DL) hardware is deployed, respective dummy light (DL) hardware being deployed at fewer than the plurality of the nodes of the optical communications network, the respective DL hardware deployed at a particular node configured to supply dummy light to each optical section extending from the particular node, and defining a respective single-section DL path between each identified pair of adjacent DL-equipped nodes; identifying one or more pairs of non-adjacent DL-equipped nodes at which DL hardware is deployed, and defining a respective multi-section DL path between each identified pair of non-adjacent DL-equipped nodes; and causing the deployed DL hardware to supply DL light to each of the single- and the multi-section DL paths.
