Abstract: 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 Nth-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.

Abstract: A gain adjuster, a gain adjustment method, and an optical line terminal are provided, to separately adjust a gain of a to-be-adjusted optical signal. The gain adjuster includes a light spot conversion component and a gain medium that are sequentially coupled. The gain adjuster further includes a pump laser. The light spot conversion component is configured to adjust light spot sizes of at least some optical signals in received optical signals to output a first optical signal transmitted in space. The pump laser is configured to excite the gain medium. The gain medium is configured to adjust a gain of the first optical signal to output a second optical signal.
