<p>An optical signal transmission method and device, and an optical transmitter. The optical signal transmission method comprises: acquiring a power of a first optical signal correspondingly output by each carrier after a modulator modulates at least one carrier; according to the transmitted amplification gain after combining the first optical signal, which is correspondingly output by at least one carrier, and the wavelength of the carrier, determining a power adjustment coefficient of a corresponding first optical signal; and according to the power adjustment coefficient of the first optical signal, adjusting the power of the corresponding first optical signal in a modulator. The optical signal transmission method and device, and the optical transmitter can adjust the power of each carrier according to the amplification gain of an optical signal and the wavelength of a carrier in a transmission link, so as to adaptively guarantee the smoothness of the gain of the optical signal in the transmission link; and the use of a pump laser or an optical amplifier and the like in an optical signal transmission system can be reduced and even avoided, reducing the OSNR cost of an optical signal transmission process.</p> |
