The present invention relates to a height-adjustable optical module test fixture. A base on a test board is connected to a fixed block. The fixed block has a cavity formed on two opposite sides thereof, facing a connector on the test board. A heating/cooling module is fixed on the upper and lower surfaces of the fixed block. A movable block is inserted into the cavity, which is in close contact with the bottom surface of the cavity. The upper surface of the movable block is a horizontal surface. The lower surface of the movable block is a first inclined surface inclined upward along its insertion direction. The bottom surface of the cavity is a second inclined surface parallel to the first inclined surface. The first inclined surface of the movable block increases or decreases the height between its upper surface and the top surface of the cavity during movement along the second inclined surface in the insertion direction. The beneficial effect is that when the optical module is heated or cooled by the heating/cooling module, since the upper and lower surfaces of the optical module structure can be in close contact with the test fixture, there is no heating or cooling of the air, thereby making it possible to relatively accelerate the heating or cooling speed of the optical module and shorten the test time.
