Shandong UHV Power Transmission Project Communication System

Products Used：

PDH Optical Multiplexer + Multi-Service Fiber Multiplexer (supports E1 + Ethernet + voice multiplexing)

Project Background

The ±800kV Longdong–Shandong UHVDC transmission project by State Grid is a key energy infrastructure in China. It places high demands on the reliability and multi-service capacity of the communication system.

Solution

The project deployed PDH optical multiplexers and multi-service fiber multiplexers to handle E1 signal and multi-service transmission (Ethernet, voice, serial data), forming a robust and efficient power communication network.

Application Scenarios

Long-distance voice transmission between substations

Ethernet data access for power SCADA systems

Transmission of serial control signals for substation equipment

Project Outcome

The system enables unified multi-service transmission between control centers and substations, ensuring stable communication for dispatching and operational data. It provides strong communication support for the UHV project.
