Communication equipment technical services

Transmission networks

Optical transmission equipment: We professionally deploy OTN/WDM, SDH/MSTP and other equipment, perform precise fiber splicing and testing, and build large-capacity, self-healing backbone transmission rings to provide reliable pipelines for various services.

Synchronous network equipment: We accurately install time synchronization (PTP) and frequency synchronization (SyncE) equipment to provide nanosecond-level time references for smart substations, wide-area measurement, and other services.

Information networks

Dispatch data network equipment: We professionally install dispatch routers, vertical encryption authentication devices, and power-specific switches, strictly following the principles of “security zoning, dedicated networks, horizontal isolation, and vertical authentication” to build a secure communication fortress for real-time grid control.

Dispatch exchange and administrative exchange equipment: We install IADs, IP-PBXs, and dispatch consoles with strong-insert, strong-removal, and conferencing functions to ensure clear dispatch voice and smooth command delivery.

Integrated data network equipment: We install enterprise-grade routers, switches, and firewalls to build flexible and efficient enterprise communication networks that support office work, video, and mobile operations.

Environment monitoring and communication power supply: We install intelligent environmental monitoring sensors, high-frequency switching power supplies, and UPS systems to provide stable and visualized power and environmental support for communication equipment.
