Abstract

Embodiments of the present invention provide an optical fiber amplifier control method, device, system, transmission node, and storage medium. Multiple WDM transmission systems are deployed between a first communication end and a second communication end, and at least one target WDM transmission system includes a first communication end and a second communication end. A transport node and a second transport node. The first transmission node receives the first control signal containing the identity of the second transmission node sent by the second transmission node, if it is determined that the first control signal is a normal control signal and the identity of the second transmission node matches the pre-stored first reference node identity, Then, the optical fiber amplifier at the transmitting end in the first transmission node is turned on. When the second transmission node receives the second control signal containing the identifier of the first transmission node and sent by the first transmission node, a similar determination is performed to turn on the optical fiber amplifier at the transmitting end in the second transmission node. Through this scheme, the accurate switching control of the optical fiber amplifier in the WDM transmission system is realized, and the data security is ensured.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to an optical fiber amplifier control method, device, system, transmission node and storage medium. Background technique [0002] With the development of cloud computing, the demand for interconnection bandwidth is increasing rapidly. The interconnection between communication subjects such as data centers (Digital Center, DC for short) generally adopts one or more wavelength division multiplexing (Wavelength Division Multiplexing, WDM for short) transmission. system to provide high-capacity interconnection. Dense Wavelength Division Multiplexing (DWDM for short) transmission system is widely used at present. [0003] In order to meet the needs of long-distance transmission, the WDM transmission system will amplify optical signals through optical fiber amplifiers, such as Erbium Doped Fiber Amplifier (EDFA for short). At full load, the optical power of the optic...
