Abstract
A chromatic dispersion measurement method is provided. According to the method, chromatic dispersion sequence processing is performed on acquired frequency domain data to obtain chromatic dispersion sequences of frequency domain data. A correlation operation on the obtained chromatic dispersion sequences is separately performed at a preset interval. A sum of obtained correlation values is calculated to obtain a first value. A chromatic dispersion value is determined according to the first value, a frequency value per unit frequency interval of the frequency domain data and the preset interval. In this way, the chromatic dispersion value can be accurately determined, and the processing efficiency is high.
