Title:
FIBER AMPLIFIER CONTROL METHOD, APPARATUS AND SYSTEM, TRANSMISSION NODE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/011374
Kind Code:
A1
Abstract:
A fiber amplifier control method, apparatus and system, a transmission node, and a storage medium. A plurality of WDM transmission systems are deployed between a first communication end and a second communication end, and at least one target WDM transmission system comprises a first transmission node (b1) and a second transmission node (a1). The first transmission node (b1) receives a first control signal that is sent by the second transmission node (a1) and comprises an identifier of the second transmission node (401); and if it is determined that the first control signal is a normal control signal and the identifier of the second transmission node matches a pre-stored identifier of a first reference node, a transmit-end fiber amplifier (C) in the first transmission node (b1) is turned on (402). When the second transmission node (a1) receives a second control signal that is sent by the first transmission node (b1) and comprises an identifier of the first transmission node, a similar determination is made so as to turn on a transmit-end fiber amplifier (A) in the second transmission node (a1). Thus, accurate switch control of a fiber amplifier in a WDM transmission system is implemented, and data security is ensured.
