Abstract
A method to select a number of fibers for ROADM-equipped nodes of an optical network by which a controller is operative to determine which links are utilized as well as their usage frequencies and then partition a scale of usage frequencies into a number of intervals. By assigning a number of fibers to each one of the intervals, a number of fibers is assigned to each link, according to their usage frequencies, setting the degree for ROADMs at the nodes. Simulations can evaluate the network's performance in terms of a blocking rate representing an overall signal blocking rate by the ROADMs at network nodes. The number of intervals, their ranges, and the number of fibers associated with each interval can be iterated until an improved or satisfactory network performance is achieved.
