Title:
OPTICAL NETWORK NODE AND OPTICAL NETWORK SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/027255
Kind Code:
A1
Abstract:
The present application belongs to the technical field of optical communications. Disclosed are an optical network node and an optical network system. The optical network node comprises a target optical amplification assembly and a light-splitting device, wherein the light-splitting device is coupled to both an input end and an output end of the target optical amplification assembly, such that a loop is formed between the output end and the input end of the target optical amplification assembly; the light-splitting device is used for splitting an optical signal from the output end of the target optical amplification assembly into multiple optical signals, and outputting same, one optical signal being transmitted to the target optical amplification assembly by means of the loop; and the optical network node generates a control optical signal in the loop by means of the target optical amplification assembly, and the power of the control optical signal is determined on the basis of the power of a service optical signal received by the target optical amplification assembly. The present application can reduce the effect of wave enhancement or wave loss on the performance of an optical network system.
