Method and System for Compensating for Optical Impairment in an Optical Signal

摘要

Methods and systems are provided for compensating impairment of a signal in an optical network. A method may include: (i) recording, for each node of a plurality nodes of the network, traffic management information specific to such node; (ii) communicating, by each node, its associated traffic management information to one or more other nodes; (iii) receiving, at a particular node of the plurality of nodes, the traffic management information communicated from the one or more nodes; (iv) determining, by the particular node, digital signal processor tap coefficients for a digital coherent receiver integral to the particular node based on at least a portion of the traffic management information; and (v) compensating, by the digital coherent receiver, optical impairment of the optical signal based on at least the determined digital signal processor tap coefficients and processing of the optical signal by a digital signal processor integral to the digital coherent receiver.
