Network architecture and networking method of optical fiber early warning system

The invention discloses a network architecture of an optical fiber early warning system and a networking method, the network architecture comprises a main server connected with a head station and a standby server connected with a tail station, and a plurality of early warning hosts are connected between the head station and the tail station through self-built optical communication links. The main server, the self-built optical communication link and the standby server form a main link; the standby server is connected with a 5G CPE terminal, and the main server, the 5G CPE terminal and the standby server form a standby link. According to the invention, after the self-established optical communication link is interrupted, the normal operation of the early warning system is maintained through the standby link, and the fiber breakage warning information detected in the early warning equipment host is transmitted to the early warning system management platform server in time, so that the data validity is ensured.
