Transmission networks
Installation, commissioning, service cutover, maintenance, and technical services for optical transmission networks such as SDH, PTN, and OTN.
Information networks
Installation, commissioning, data debugging, service cutover, maintenance, and technical services for information network equipment such as firewalls, routers, and switches.
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.
