Optical fiber transceiver with cooling device

The utility model belongs to the technical field of optical fiber transceivers, and particularly relates to an optical fiber transceiver with a cooling device, which comprises a hollow outer shell with openings at the left end and the right end, an end cover is arranged at the opening at the left end of the outer shell, and a cooling driving cover is arranged at the opening at the right end of the outer shell. An air outlet and an air inlet are formed in the left end and the right end of the cooling driving cover respectively, the left end of the cooling driving cover communicates with an opening in the right end of the outer shell, and a cooling fan is arranged in the cooling driving cover. The heat dissipation holes are opposite to the heat dissipation fan, so that heat on the surface of the transceiver circuit structure is directly brought out of the outer shell by flowing air, heat dissipation is achieved, heat generated on the surface of the transceiver circuit structure can be dissipated upwards through
