  description: "The SDH equipment is a new generation of products based on SDH/MSTP technology launched by our company in response to market demand. It can meet the needs of users for broadband and narrowband multi-service fiber optic transmission and access, while also satisfying higher-capacity user requirements and providing more reliable communication protection. The IDM MSTP155-24 can directly interface with remote PDH optical terminals, optical modems, and multi-service optical terminals, adapting to various network topologies. It can serve as a compact MSTP device integrating multi-service access, SDH transmission, and PDH optical access functions. The concise and comprehensive network management functions enable configuration, fault query, and data statistics for this series of equipment, with real-time monitoring of network operation status. Additionally, industrial-grade components and comprehensive EMC and interface protection designs are adopted throughout."
