Abstract
An optical communication apparatus according to an embodiment of the present invention includes: a light emitting element; a transmission driver that drives the light emitting element; a light receiving element capable of changing a multiplication factor by a bias voltage; a temperature sensor; a computing unit that calculates a drive rate of the transmission driver; and an adjusting unit that adjusts the bias voltage applied to the light receiving element. The adjusting unit adjusts the bias voltage by linear computation using a plurality of target values of the bias voltage for combinations of a plurality of temperatures and a plurality of drive rates, based on a temperature detected by the temperature sensor and a result of calculation of the drive rate.
