Ring network
Schematic diagram of networking：
◆ Multiple stations use 2-core ring optical fiber to build a ring transmission network with WDM equipment, which can support a maximum transmission capacity of 25.6T (400G*64 waves) on the ring, which greatly saves optical fiber resources
◆ Provides a comprehensive service protection solution with a failover time of < 50ms
◆ Any node on the ring can communicate with each other, the optical layer is directly connected, and the network is flattened, improving service latency and jitter performance
◆ The in-band OSC can realize the interconnection of network management signals of each site, and the entire network can be managed by single site access
