A method for optical generation and long-distance transmission of millimeter-wave signals is proposed in this paper. Two phase-dependent dual-wavelength laser beams are generated by a dual-wavelength laser. After long-distance transmission through the optical fiber, A beat signal can be generated. In this study, the frequency of signal can reach 24.640 GHz within 1km transmission distance. Although the beat signals above 30 GHz cannot be observed due to equipment limitations, an uncomplicated method has been shown in generating and long-distance transmission of millimeter-wave signals. Also, the method has its unique advantages of avoiding interference and electromagnetic pollution.
