Abstract: This application provides an example light source switching apparatus. The apparatus includes first and second multi-mode interference (MMI) couplers, and a phase modulator. The first MMI coupler includes four ports, where first and second ports are located on one side, and third and fourth ports are located on the other side. The second MMI coupler includes three ports, where fifth and sixth ports are located on one side, and a seventh port is located on the other side. The first and the second ports connect to the fifth and the sixth ports, respectively, to form two connections. The phase modulator is disposed on one of the two connections, and the seventh port connects to an optical modulator. Both the third and the fourth ports connect to a light source emitting continuous light, and the phase modulator selects one of the two light sources for output from the seventh port.

Abstract: An optical distribution network ODN apparatus includes an optical splitting module, a control chip, a first optical port connected to the OLT, a second optical port connected to a next-level ODN apparatus, and a plurality of third photoelectric composite ports connected to the plurality of ONUs. The control chip sends a plurality of electrical signals that carry the port identification information to the plurality of corresponding ONUs. The optical splitting module performs power splitting on a first optical signal sent by the OLT to obtain a second optical signal transmitted to the next-level ODN apparatus and a plurality of third optical signals transmitted to the plurality of ONUs. The optical splitting module can be further configured to separately receive upstream optical signals of the plurality of corresponding ONUs and to transmit the upstream optical signals carrying identification information of the ONUs to the OLT.
