Dispersion compensation design method and dispersion compensation design system

摘要

A dispersion compensation design system includes a segment dividing unit to divide an optical network into segments of a linear network or a ring network, a path classifying unit to classify one of paths of the optical network, as a specific type path, the one of the paths being incapable of transmitting an optical signal and contained in a longer path having a route longer than that of the one of the paths and capable of transmitting the optical signal, a segment reconfiguration unit to reconfigure the segments so as to maximize a number of the specific type paths, a dispersion compensation amount computing unit to compute a dispersion compensation amount in any of spans of the optical network so as to minimize the number of the specific type paths within the reconfigured segment, and an update unit to update the dispersion compensation amount with the computed dispersion compensation amount.

1. A dispersion compensation design system, comprising:
a segment dividing unit configured to divide an optical network into a plurality of segments of a linear network or a ring network; a path classifying unit configured to classify one of paths of the optical network, as a specific type path, the one of the paths being incapable of transmitting an optical signal by itself and contained in a longer one of the paths having a route longer than that of the one of the paths and capable of transmitting the optical signal; a segment reconfiguration unit configured to reconfigure the segments so as to maximize a number of the specific type paths; a dispersion compensation amount computing unit configured to compute a dispersion compensation amount in one of spans of the optical network so as to minimize the number of the specific type paths within the reconfigured segment; and an update unit configured to update the dispersion compensation amount in the one of the spans of the optical network with the computed dispersion compensation amount obtained by the dispersion compensation amount computing unit.
