铁路通信工程在铁路各项工作开展中承担着非常重要的角色,是保证铁路行车安全、提高运输效率的重要工程.当前,我国铁路网已经基本于全国实现建设,铁路网相互交织,且一些铁路还延伸至比较偏僻的地方,铁路通信工程显得更加重要.在铁路通信工程中,接入网技术是支撑其运行的关键技术.随着时代及科技的发展,目前有许多不同的接入网技术.对此,将着重分析有线接入网技术在铁路通信工程中的应用.%Railway communication engineering plays a very important role in the development of various railway projects. It is an important project that ensures the safety of railways and improves the transportation efficiency. At present, China, s railway network has basicallyb een built in the country, railway networks are intertwined, and some railways are also extended to more remote places. Railway communication projects are even more important. In the railway communication engineering, the access network technology is the key technology supporting its operation. With the development of the times and technology, there are many different access network technologies. In this regard, this article will focus on the application of wired access network technology in railway communications engineering.
