Optical device, optical transceiver assembly and related equipment

The embodiment of the utility model provides an optical device, an optical transceiver assembly and related equipment which can be applied to an FTTR scene. And the optical device is used for converting the electric signal into an optical signal for transmission, or converting the optical signal into the electric signal. The optical device is provided with a base, and the base comprises a base body and an electrical pin. The base body comprises a first surface, a second surface and a side face, the first surface and the second surface are oppositely arranged, the side face is connected to the first surface and the second surface, the side face comprises an installation plane, and the installation plane is used for covering the heat conduction pad to be connected with a shell component of the optical communication equipment so that heat generated by the optical device can be conducted to the shell component through the heat conduction pad. The electrical pins are arranged on the second surface, and the electrical pins are used for being electrically connected with a circuit board of the optical communication equipment. As the heat conduction pad covers the mounting plane, the contact area and the heat dissipation area of the side surface and the heat conduction pad are increased, the heat dissipation efficiency of the optical device is improved, the optical device can work normally at the working temperature, and the optical performance of the optical device is improved.
