摘 要:随着我国近10年来城市轨道交通系统建设的全面提速,20多个城市同时在建设地铁,通信传输系统在轨道交通的运行控制、安全保障中发挥了重要的作用。城市轨道交通线路中大量先进设备的使用以保障乘客的安全及高效出行。光传输网络以其可靠性高、带宽大和低噪声作为城市轨道交通通信网的最优选择。但是,由于地铁线路的线路里程及性质不同,所需要的光纤通信网的规模或组网方式也有所不同。本文本着既注重投资预算,又适应新技术发展需求的原则,对五种主流光传输网络制式的特点详细分析,为城市轨道交通通信光传输网建设提供帮助。Along with the overall acceleration of the construction of urban rail transit system in our country for near- ly 10 years, more than 20 cities are in the construction of the subway at the same time, communication transmission system plays an important role in the operation of the rail traffic control and safety control. A large number of ad- vanced equipment is used in urban rail transit lines to ensure the safety of the passengers and efficient travel. With its high reliability, bandwidth and low noise, optical transmission network is the optimal selection of urban rail tran- sit network. However, due to the mileage line and different nature of subway line, which needs different size of the optical fiber communication network and network mode. Based on the principle of focusing on the investment budget and adapting to new technology development needs, the features of five main systems of optical transmission network are analyzed in detail, this paper aims to improve the urban rail transit construction of communication optical trans- mission network.
