光端机,只是高速公路机电系统中基础环节产品。但对于整个系统来说,它是音视频、数据传输不可或缺的关键。近年来随着我国高速公路里程持续高速增长,联网收费、联网监控的全面推行、隧道桥梁监控备受重视,对于监控系统的要求不断提高。作为监控系统传输重要组成部分的光端机,其品质优劣直接影响整个系统。 Guangduan Ji, only highway mechanical and electrical systems in the basic aspects of products. But for the entire system, it is audio and video, the key to data transmission is indispensable. In recent years, with the continuous high-speed growth of China’s highway mileage, network charges, the full implementation of network monitoring, monitoring of the tunnel bridge pays close attention to the monitoring system requirements continue to increase. Optical transmission as an important part of the monitoring system transmission, the quality of the direct impact on the quality of the entire system.
