<P>PROBLEM TO BE SOLVED: To optimally design a dispersion compensation amount in each chromatic dispersion compensation device so as to satisfy desired optical signal quality at a terminal node, while considering the residual chromatic dispersion during the transmission, for each wavelength path on an optical network. <P>SOLUTION: A residual chromatic dispersion target value at a terminal node is set for each wavelength path, and also, candidates of the dispersion compensation amount settable in each chromatic dispersion compensation device on the optical network are set. Computation processing is executed for selecting the dispersion compensation amount in each chromatic dispersion compensation device from the set candidates so that the sum of errors between the residual chromatic dispersion amounts and the set residual chromatic dispersion target values at the terminal nodes for all of wavelength paths becomes minimum. <P>COPYRIGHT: (C)2009,JPO&INPIT |
