An optical power value transmission method includes obtaining optical multiplexing section link information, determining a first output port of the source network device based on the optical multiplexing section link information, obtaining a first output power value of an optical signal, and sending the first output power value to the downstream network device by the first optical fiber. The optical multiplexing section link information is useable to indicate an optical fiber connection relationship between two adjacent network devices between a source network device and a target network device. An optical multiplexing section includes two adjacent network devices, the source network device and the target network device. The source network device and the target network device are in different data communication networks. The downstream network device is connected to the source network device, and is indicated by the optical multiplexing section link information.
