Optical Receive Component, Combination Transceiver Component, Combination Optical Module, OLT, and PON Systems

摘要

Embodiments of the present application provide a receiver optical sub-assembly, a combo bidirectional optical sub-assembly, a combo optical module, an optical line terminal, and a passive optical network system, and are related to the field of optical communication technologies. This receiver optics sub-assembly comprises a first transistor-outline can, a first transistor with a light incidence hole disposed on the outline can, wherein the first transistor-outline can includes a first demultiplexer, a first optical A receiver, a second optical receiver, and an optical lens combination are packaged. Light enters the first demultiplexer through the light incidence hole, the first demultiplexer configured to transmit an optical signal of a first wavelength and reflect an optical signal of a second wavelength. The first optical receiver is disposed on a transmit optical path of the first demultiplexer, and the first optical receiver is configured to receive an optical signal of a first wavelength. The optical lens combination is disposed on the reflective optical path of the first demultiplexer, the optical lens combination configured to guide an optical signal of a second wavelength reflected by the first demultiplexer to a second optical receiver. The second optical receiver is configured to receive an optical signal of a second wavelength.
