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
