摘要
根据当前通信技术的发展状况,对城市轨道交通建设中的通信传输系统方案进行探讨,包括开放式传输网络(OTN)、光同步数字传输网(SDH)及异步传输模式(ATM)三种方案,并对各方案的特点进行分析。
On the basis of the development of communication technology, the scheme of communication transmission system in urban rail transit construction is discussed. Open Transport Network (OTN), Synchronous Digital Hierarchy (SDH), and Asynchronous Transfer Mode (ATM) are introduced, and the characteristics of each scheme are analyzed.
