APPARATUS FOR CALCULATING CHROMATIC DISPERSION, AND METHOD THEREFOR, AND SYSTEM FOR MEASURING CHROMATIC DISPERSION, AND METHOD THEREFOR, AND THE RECORDING MEDIA STORING THE PROGRAM PERFORMING THE SAID METHODS

摘要

A device and a method for calculating the CHROMATIC DISPERSION, a system and a method for measuring the CHROMATIC DISPERSION and a RECORDING MEDIUM storing a program implementing the method for the same are provided to make simplification of the device with a simplified method. A method for calculating the chromatic dispersion comprises: a step of generating a plurality of sub-spectrum groups by applying a Gaussian filter group in an input signal with the interference component; a step of extracting a peak component from a plurality of sub-spectrum groups and calculating a time delay value(S315); a step of generating a function for the chromatic dispersion calculation which has the frequency and time delay value of the peak component as variable using the function for fitting(S320); and a step of calculating the chromatic dispersion using the generated chromatic dispersion calculation function(S325).
