SDH Equipment Application Case

Multiple SDH devices form two tangent ring networks at different levels. Each SDH device in the ring network can form a star or ring network with other SDH devices, PCM devices, and user devices, enabling flexible networking in different application environments.

Various services between the two tangent ring networks can be cross-connected through the SDH devices at the tangent points, achieving non-blocking transmission of various services across different networks, effectively expanding the transmission capacity of the communication network.

The SDH ring network provides strong channel protection capability and abnormal alarm reporting capability. When a network transmission anomaly occurs, the central end will detect it in time, providing a solid basis for fault location and timely troubleshooting.

SDH devices feature optical interfaces at different levels and a rich set of service interfaces, supporting further expansion of complex networks.

Through the gateway device in the network, other devices across the entire network can be monitored and managed online in real time.
