Abstract
An optical receiving device includes: a conversion device that converts an input burst optical signal into a positive phase electrical signal and a negative phase electrical signal; an amplification device that amplifies the positive phase electrical signal and the negative phase electrical signal; a first output terminal that outputs the positive phase electrical signal; a second output terminal that outputs the negative electrical signal; a first transmission line that couples the amplification device with the first output terminal and transmits the positive phase electrical signal; a second transmission line that couples the amplification device with the second output terminal and transmits the negative phase electrical signal; and a control device that reduces a potential difference between the first transmission line and the second transmission line in a no-signal period that is provided between burst optical signals.
