Abstract:
1. A chromatic dispersion compensation designing method of, in an optical network including a plurality of nodes connected to each other via optical transmission paths, setting a dispersion compensation amount in the chromatic dispersion compensation performed on a plurality of wavelength paths indicating routes from starting nodes to terminal nodes of a plurality of optical signals transmitted over the optical network, comprising processes of: inputting with optical network information; setting a residual chromatic dispersion target value at the terminal node for each wavelength path, based on the optical network information; setting candidates of the dispersion compensation amount in a plurality of chromatic dispersion compensation modules arranged on the respective wavelength paths; and executing computation processing of selecting the dispersion compensation amount in each chromatic dispersion compensation module from the candidates so that the sum of errors between residual chromatic dispersion values and the residual chromatic dispersion target values at the terminal nodes for all of wavelength paths becomes minimum.
