Abstract:
Methods and apparatus for determining transmission power of a plurality of optical channels for transmission of the channels along respective paths obtained through an optical transmission system. Information is obtained indicative of the path of each channel through the optical transmission system, and each channel is allocated to a group of channels in dependence upon the obtained information. A quality metric is determined for each group of channels, and a total transmission power for each group is determined in dependence upon the determined quality metric.
