An object is to provide an optical transmission apparatus in which, even if a change is made in the bit rate of modulation signals that are inputted to a plurality of optical modulating units, the modulation signals do not suffer from phase shifting, thereby enabling achieving synchronous modulation in the plurality of optical modulating units and enabling achieving a high optical signal quality. An optical transmission apparatus comprises: a plurality of optical modulating units that modulate light on the basis of modulation signals; and a delay amount control unit that, based on bit rate information indicating a bit rate of the modulation signals, controls delay amounts of the modulation signals to be inputted to the plurality of optical modulating units, in such a way that the light is modulated in a synchronous manner in the plurality of optical modulating units. |
