Abstract: A first optical transmission device includes a plurality of first lasers having a different corresponding wavelength, a first optical path component, a first modulator, and a first processor portion. The plurality of first lasers is connected to a plurality of optical input ports of the first optical path component respectively. The first optical path component is configured to perform multiplexing on continuous light of different wavelengths emitted by the plurality of first lasers, and perform power splitting of multiplexed continuous light thereby obtaining two paths of continuous light, send a first path of continuous light to the first modulator, and send a second path of continuous light to a second optical transmission device at a peer end. The first processor portion is configured to send a first analog signal to the first modulator. The first modulator is configured to at least modulate the first analog signal onto the first path.
