Abstract: A wavelength switching method, apparatus, and system are disclosed. The method includes: encapsulating a logical link identifier (LLID) of an optical network unit (ONU) and a wavelength allocated to the ONU into a first Multi-Point Control Protocol (MPCP) message, and sending the first MPCP message to the ONU, for the ONU to perform switching according to the wavelength. In this manner, a problem of how to implement wavelength switching in a next-generation Ethernet passive optical network (NG-EPON) is resolved.

Abstract: Embodiments of the present invention provide an optical network unit (ONU) registration method, an apparatus, and a system. The ONU registration method includes: scanning, by an ONU port, a downstream wavelength channel, where the ONU port is one of a plurality of ONU ports on an ONU; receiving, by the ONU port, a discovery grant message from an optical line terminal (OLT), where the discovery grant message includes a channel identifier of a downstream wavelength channel on which the discovery grant message is being transmitted; sending, by the ONU port, a register request message to the OLT, where the register request message includes a port number of the ONU port; and receiving, by the ONU port, a register message from the OLT, where the register message includes the port number of the ONU port and an ONU logical identifier allocated by the OLT to the ONU port.
