Optical receiving assembly and optical module

The utility model relates to the technical field of optical communication, and provides an optical receiving assembly, which comprises a shell and a wavelength division multiplexer arranged in the shell, and further comprises a wedge angle sheet used for deflecting an incident light angle, the wedge angle sheet is arranged on one side, close to a light inlet of the shell, of the wavelength division multiplexer, and the wedge angle sheet is arranged on the other side of the wavelength division multiplexer. Incident light is deflected by the wedge angle sheet and then enters the wavelength division multiplexer at an angle of 13.5 degrees. The utility model further provides an optical module which comprises a light emitting assembly and further comprises the light receiving assembly, and the light receiving assembly and the light emitting assembly are arranged side by side. According to the utility model, the wedge angle sheet is additionally arranged on the optical path between the wavelength division multiplex
