Abstract:
An optical receiver includes an analog/digital converter, and a control circuit. The analog/digital converter has a dynamic range at a time of converting an analog electric signal generated based on an optical signal to a digital electric signal. The dynamic range is variable, and the control circuit varies the dynamic range of the analog/digital converter based on the chromatic dispersion of the optical signal.
