Abstract: with the development of China's economy and science and technology, a large number of advanced technologies are generated in China's communication engineering. The speed of communication technology innovation is faster and faster, and it is more and more widely used in people's production and life, which also promotes the development of communication technology in China to a certain extent. In communication engineering, wired transmission technology provides more convenience for people's communication. Therefore, it is particularly important to optimize the wired transmission technology in communication engineering. This research is based on the analysis of the application characteristics of cable transmission technology in communication engineering, and puts forward some improvement suggestions on its current situation, so as to promote the development of cable transmission technology in communication engineering in China.

1. 通信工程、傳输技术概念及分类
1.1 通信工程概念
通信工程属于电子信息,也常被称之为电信工程。在早期时,通信工程主要通过电磁波技术进行信号传输,后来逐渐朝短波长、宽频带方向发展,传媒介质也从光传媒气体管道发展为玻璃纤维。据相关调查结果发现,光纤技术是目前有线网络传输中应用最广泛的传输技术,具有良好传输前景。随着电磁场理论出现,磁波通讯技术在人们生活中得到推广,通讯波也逐步由短波演变为长波,信号传输范围得到扩大,大大的提升了光通讯的传输速度和传输量,PHD设备的问世,更是实现了点到点传输,传输速度得到进一步提升。
1.2 传输技术分类
目前,我国通信工作主要通过无线和有线两种方式进行传输,其中又以有线传输技术最为常见,在传输过程中主要通过光电信号和电波实现信息传送,在信号传输过程中,多以电缆、光纤作为介质,在数据传输时不仅效率高密切稳定性好。……
