CHROMATIC DISPERSION MEASUREMENT METHOD AND DEVICE AND DIGITAL COHERENT RECEIVER |
摘要 |
A chromatic dispersion measurement method, a chromatic dispersion measurement device and a digital coherent receiver. The chromatic dispersion measurement method comprises: performing chromatic dispersion sequence processing on acquired frequency domain data to obtain chromatic dispersion sequences of the frequency domain data (201); separately performing a correlation operation on the obtained chromatic dispersion sequences at a preset interval, and calculating a sum of obtained correlation values to obtain a first value (202); and determining a chromatic dispersion value according to the first value, a frequency value per unit frequency interval of the frequency domain data and the preset interval (203). In this way, the chromatic dispersion value can be accurately determined, and the processing efficiency is high. |
