Method and apparatus for controlling optical fiber amplifier, system, transmission node and storage medium

An apparatus for controlling an optical fiber amplifier, applied to an optical fiber communication system, wherein the optical fiber communication system comprises a first communication end and a second communication end, a plurality of wavelength division multiplexing transmission systems are deployed between the first communication end and the second communication end and comprise at least one target wavelength division multiplexing transmission system;

• the target wavelength division multiplexing transmission system comprises a first transmission node and a second transmission node;
• the apparatus is located at the first transmission node and comprises:
• a processor;
• a memory for storing an instruction executable by the processor;
• wherein the instruction, when executed by the processor, causes the processor to:
• receive, through an optical supervisory channel, a first control signal sent by the second transmission node, in response to a recovery of an interrupted optical fiber between the first transmission node and the second transmission node, wherein the first control signal comprises an identifier of the second transmission node;
• switch on a transmit-end optical fiber amplifier of the first transmission node which has been switched off, based on if determining that the first control signal is a preset normal control signal and that the identifier of the second transmission node matches a pre-stored first reference node identifier;
• send, through the optical supervisory channel, a second control signal comprising an identifier of the first transmission node to the second transmission node, such that the second transmission node switches on, when determining that the second control signal is a preset normal control signal and that the identifier of the first transmission node matches a pre-stored second reference node identifier, a transmit-end optical fiber amplifier of the second transmission node which has been switched off.
