OPTICAL RECEPTION DEVICE AND OPTICAL RECEPTION METHOD

WIPO Patent Application WO/2021/181568

A1

An optical reception device comprising: a chromatic dispersion compensation unit that subjects each received signal to chromatic dispersion compensation, said received signals being obtained by using a coherent detection method to receive optical signals that were modulated according to a subcarrier modulation method, and said received signals having been divided by subcarrier; and a plurality of delay compensation units that compensate for inter-subcarrier delay in the received signals of each subcarrier that were subjected to chromatic dispersion compensation.
