摘要： The objective of the present invention is to realize a chromatic dispersion compensation method which does not depend on a wavelength path in a photonic network to which a HUB node is applied and its monitoring control. In order to achieve this purpose, the present invention controls a plurality of variable chromatic dispersion compensators arbitrarily disposed in the photonic network based on the measured results of a plurality of chromatic dispersion monitors arbitrarily disposed in the photonic network and wavelength path information kept by the network management system which manages the entire photonic network. Here, the variable chromatic dispersion compensator within the network that should be controlled and the chromatic dispersion compensated quantity thereof are determined based on the measured results of the chromatic dispersion monitor and the wavelength path information kept by NMS.

摘要： A chromatic dispersion compensation method is disclosed that compensates for chromatic dispersion in an optical transmission line. Dispersion compensators provided one for each of first dispersion compensation segments, each of which constitutes a predetermined length of the optical transmission line, are set such that a residual dispersion slope in each of the first dispersion compensation segments becomes positive. Then, dispersion slope compensators provided one for each of second dispersion compensation segments, each of which includes a predetermined number of the first dispersion compensation segments, are set to have a negative dispersion slope such that residual dispersion slopes in each of the second dispersion compensation segments becomes zero.
