| 英文摘要 | An optical transmitting apparatus includes a variable optical attenuator of a magneto-optical effect type disposed by spatial coupling between a light source and an optical fiber, the variable optical attenuator configured to attenuate light output from the light source and coupled to the optical fiber, according to an input driving voltage; a generator configured to generate the driving voltage of the variable optical attenuator based on information to be superimposed on the light by the variable optical attenuator, the generator inputting the generated driving voltage into the variable optical attenuator; and a controller configured to control a bias of the driving voltage generated by the generator, the controller controlling an amplitude of the driving voltage generated by the generator, based on data according to characteristics between the driving voltage and an attenuation amount of the light by the variable optical attenuator. |
