Patent abstract
The present invention discloses a design method of wavelength dispersion compensation of a desired link that is extracted from an optical network, the link including two or more spans, and two or more nodes (N1, N4) that are equipped with an add/drop function, as shown in FIG. 2. All residual dispersion ranges of paths that reach corresponding nodes are adjusted to fall within predetermined tolerable residual dispersion ranges that are set up for all the paths of the link by adjusting wavelength dispersion compensators provided to each of the spans.
