Abstract
An optical transmitter, including a wavelength selector and a plurality of modulator groups, is proposed. Each modulator group includes a plurality of modulators, and operating wavelengths of any two modulators in each modulator group are different. The wavelength selector is configured to: obtain a first beam from a multi-wavelength light source, and generate a second beam based on the first beam, where the second beam includes some of the plurality of wavelengths of the first beam. A modulator in a modulator group of the plurality of modulator groups is configured to modulate to-be-sent data onto a wavelength in the second beam.
