  • Chromatic dispersion detection method and device for optical transmission network and storage medium
    Patent number: 10153847
    Abstract: The disclosure discloses a Chromatic Dispersion (CD) detection method for an optical transmission network. Data of two polarization states orthogonal to each other is converted from time-domain data to frequency-domain data, extraction is performed on the frequency-domain data and a linear combination operation is performed on the extracted frequency-domain data, an argument of a CD value of the data of the two polarization states are obtained according to a result of the linear combination operation, and the CD value is estimated according to the argument of the CD value of the data of the two polarization states. The disclosure further discloses a CD detection device for the optical transmission network and a storage medium.
