Disclosed is a wavelength converter. The wavelength converter comprises a reception end and a sending end. The reception end comprises: a coherent detection front-end module, used for extracting a phase and polarization information of a first light signal entering the reception end, and performing signal separation processing on the first light signal according to different phases and polarizations, a wavelength of the first light signal being a first wavelength; and a light detection module, used for detecting the processed light signal, and converting the processed light signal into an electric analog signal. The sending end comprises: a carrier light source module, used for generating a target carrier, a wavelength of the target carrier being a second wavelength; multiple linear drivers, used for enabling multiple paths of electric analog signals to be synchronously loaded into corresponding light modulation modules; and light modulation modules, used for modulating electric analog signals into the target carrier, and generating modulated light signals. The wavelength converter provided in an embodiment of the present invention has a mature forming components, needs simple preparation processes, reduces the cost, reduce power consumption, has better reliability and is easier to implement. |
