This application provides a port identification method. The method includes: obtaining reflection information of reflection peaks formed by each ONT by separately reflecting test light when the test light provided by a wavelength-tunable device is transmitted in the PON; determining, based on the reflection information of the reflection peaks, a port of a splitter corresponding to each reflection peak group, where each reflection peak group includes reflection peaks formed by a same ONT by reflecting the test light; and determining, based on first transmission information of at least one reflection peak in each reflection peak group, the port of the splitter corresponding to each reflection peak group, and second transmission information between each ONT and an OLT, a port corresponding to each ONT in the splitter. According to this application, port identification efficiency can be improved.

Port identification method and apparatus

An optical distribution network, an optical network system, a splitter, and a method for identifying a port of the splitter are provided. The optical distribution network includes a splitter, a first optical filter, and a first power change assembly. The splitter includes at least two output ports, each output port corresponds to at least one first optical filter, different output ports correspond to different first optical filters, and center wavelengths of detection light that the different first optical filters allow to pass through or do not allow to pass through are different. Each output port of each splitter in an N-level splitter corresponds to the first power change assembly, and the first power change assembly is configured to change a power of first service light based on received first detection light.
