高速公路的机电业务具有安全性要求高、业务种类繁多、每种业务的颗粒小等特点,要求传输网络成熟、稳定,数据传输要采用面向连接的传输方式,传输网络要具备灵活的业务调度能力。文章总结了光纤传输技术发展状况,光纤传输系统在高速公路机电工程中的应用以及可供高速公路选择的光纤传输技术。
The electromechanical business of the expressway has the characteristics of high safety requirements, large variety of businesses and small granularity of each business. It requires the transmission network to be mature and stable, and the data transmission should adopt the connection-oriented transmission mode. The transmission network should have flexible business scheduling capability . The paper summarizes the development of optical fiber transmission technology, the application of optical fiber transmission system in the highway electromechanical engineering and the fiber transmission technology which can be selected by expressway.
