Abstract
A method of controlling optical signal traffic in an optical network between a transmitter and a plurality of receivers, where the transmitter is adapted to compensate optical impairments based on at least one optical parameter, includes steps of identifying each path between the transmitter and the plurality of receivers, determining a respective optical parameter for each path, selecting one of the receivers for receiving an optical signal from the transmitter, and enabling the transmitter to generate the optical signal using the respective optical parameter of the path between the transmitter and the selected receiver. By preconfiguring compensation parameters for the various paths in the network, an all-optical network can be implemented wherein optical signals can be switched, added or dropped without having to match dispersion maps or perform optical-electrical-optical regeneration.
