Abstract:
A method of providing a dispersion managed link for a wavelength division multiplexed optical transmission system having a plurality of predetermined wavelengths one of which is a center wavelength, the link including a plurality of serially connected spans, each span having a length of optically dispersive fiber connected to a dispersion compensating module and being connected to an adjacent span by an optical amplifier, the method comprising the steps of:a. selecting one of a ramp dispersion map, angular dispersion map arcuate dispersion map for representing dispersion on the link; b. generating a set of dispersion maps, according to the selected dispersion map, at the center wavelength; c. simulating, for each dispersion map in the set, each wavelength to obtain a performance indicator of that wavelength; d. determining, for each dispersion map in the set, which one of the performance indicators is the minimum performance indicator; e. selecting the dispersion map with the greatest minimum performance indicator; and f. selecting dispersive fibers and dispersion compensating module for each span in accordance with the selected dispersion map.
