Zhangjiakou Chongli International Ski Resort Water Regulation SDH Optical Communication System

As a leading provider of comprehensive optical communication solutions, Beijing Ruiguang Jiyuan Digital Technology Co., Ltd. will leverage its profound technical expertise and superior product quality to focus on the specialized communication application market, supporting the water regulation optical communication system of the Zhangjiakou Chongli International Ski Resort and serving as a strong backbone for the 2022 Winter Olympics.

This solution is primarily used to achieve the transmission and access of voice services, Gigabit/100Mbps Ethernet services, and data services between the water regulation project's automatic monitoring system, video surveillance system, and various branch and trunk pump stations through an SDH optical fiber transmission system. It is based on a 622M SDH dual optical transmission ring network to realize service transmission and access. The aggregation SDH equipment at the management center provides Gigabit/100Mbps Ethernet interfaces, voice trunk interfaces, and audio interfaces. It forms a dual 622M optical fiber ring network with the various branch and trunk pump stations along the line, enabling the transmission and access of Ethernet services, video surveillance signals, telephone services, and automation control data from remote nodes. The remote SDH equipment at each trunk and branch pump station directly provides telephone interfaces, Ethernet interfaces, and audio interfaces, connecting to the telephone systems, video surveillance systems, and automation control systems of each workstation according to the access requirements of each node.
