Abstract
It is provided an optical receiver comprising a compensator, a compensation controller and a clock extractor. The optical receiver selects first and second values, and obtains a stabilization time necessary to change the dispersion value and a transition time shorter than the stabilization time, compensates the received optical signal using the selected first value, changes the dispersion value from the first value into the second value, compensates the received optical signal using the dispersion value when the transition time has passed since starting to change the dispersion value, creates second extraction information of the dispersion value after the transition time, compensates for dispersion of the optical signal using an dispersion value calculated based on the second value and the difference between the dispersion value after the transition time and the second value in a case where the created second extraction information indicates that the clock extraction is available.
