Abstract:
In the technical field of optical communication a multi-path wavelength division multiplexing light receiving component including a substrate placed at the bottom of a housing is provided. The housing and substrate form an installation chamber, and include a light emitting unit, a light de-multiplexing unit, a reflector and a light receiving unit. The light emission unit, the light de-multiplexing unit, the reflector, and the light receiving unit are located inside the installation cavity, and the light emission unit, the light de-multiplexing unit, and the reflector are fixed on the housing, and the light receiving unit is fixed on the substrate. An optical module includes the multiplex wavelength division multiplexing optical receiving component. The length of the light receiving unit is shortened by reflecting an optical signal decomposed by a light de-multiplexing unit, and disposing the light receiving unit integrally below a reflector.
