  • Patent number: 12592536
    Abstract: A method and an apparatus for controlling an optical fiber amplifier, a system, a transmission node and a storage medium. WDM transmission systems are deployed between a first communication end and a second communication end. At least one target WDM transmission system includes a first transmission node and a second transmission node. The first transmission node receives a first control signal including an identifier of the second transmission node, and switches on a transmit-end optical fiber amplifier of the first transmission node if determining that the first control signal is a normal control signal and the second transmission node identifier matches a pre-stored first reference node identifier. The second transmission node receives a second control signal including an identifier of the first transmission node, and performs a similar judgment to switch on a transmit-end optical fiber amplifier of the second transmission node.
