摘要
Embodiments of this application provide receiver optical subassemblies, combo bidirectional optical subassemblies, combo optical modules, optical network units and passive optical network systems, relating to the field of optical communication technology. The receiver optical subassembly includes a first transistor outline can, the light incident holes are located on the first transistor outline can, a first demultiplexer, a first optical receiver, a second optical receiver. And the combination of optical lenses is packaged in a first transistor outline can. The light enters the first demultiplexer through the light incident hole, and the first demultiplexer is configured to transmit the optical signal of the first wavelength and reflect the optical signal of the second wavelength. The first optical receiver is arranged on the transmitted light path of the first demultiplexer, and the first optical receiver is configured to receive an optical signal of the first wavelength. The combination of optical lenses is arranged on the reflected light path of the first demultiplexer so that the combination of optical lenses guides the optical signal of the second wavelength reflected by the first demultiplexer to the second optical receiver. It is composed of. The second optical receiver is configured to receive an optical signal of a second wavelength.
