摘要
Methods for configuring an optical link with an optimized spectral efficiency are provided. In these methods, a controller of an optical network obtains a baseline configuration that includes a traffic mode that uses a predetermined channel spacing of a plurality of channels in a frequency spectrum. The plurality of channels is used for transmitting optical signals on an optical link in the optical network. The controller further converts the SNR-margin to a Q-margin threshold value associated with a Q-margin as a performance parameter and while maintaining the performance parameter with a predetermined range of the Q-margin threshold value, varies at least one transmission parameter to reduce channel spacing. The controller also generates a spectral frequency map in which the channel spacing is reduced with respect to the baseline configuration and configures, via an optical network element in the optical network, the optical link based on the spectral frequency map.
