Abstract:
1. A wavelength dispersion compensation design method, comprising: extracting a link out of an optical network, the link containing a plurality of spans and a plurality of nodes, each of the nodes including an add/drop function; setting an amount of wavelength dispersion of a base wavelength of the spans from the extracted link, a tolerable residual dispersion range for all paths of the extracted link as a condition of the optical network being serviceable, an amount of error of residual dispersion, and an amount of distribution; and determining a combination of the amounts of wavelength dispersion compensation of wavelength dispersion compensators provided to the corresponding spans, the amounts sufficing for simultaneous inequalities that stipulate that all residual dispersion ranges of one or more paths that reach each of the nodes falls within the tolerable residual dispersion range.
