光传输在L波段卫星接收系统中的应用

Design and Application of L-Band Optical Transmission in Satellite Receiving System

近年来,光传输技术迅速发展,在信息传输中得到广泛应用。通过光传输的方式来传输L波段信号解决了传统电缆短距离传输的诸多弊端。相对于传统的电缆传输来说,光传输系统在L波段信号传输中具有更多优势,特别是智能化的光传输系统管控性更强、传输效果更好。因此,OE-LB(光电转换-L波段传输)的中频信号传输模型在很多电视台都得以推广应用。本文结合贵州广播电视台在L波段信号通过光传输系统设计应用为实例,以功能稳定性、传输效率、冗余备份等方面为要点,对OE-LB系统的信号转换、传输设计和流程监控的具体内容作详细介绍。

In recent years, optical transmission technology is rapidly developing and widely used in information transmission. L-band signal transmission through optical transmission overcomes the shortcomings of the traditional cable transmission. Compared with the traditional cable transmission, the optical transmission system has more advantages in the L-band signal transmission. Especially, intelligent optical transmission system provides more powerful, better transmission effect. As a result, the OE-LB （photoelectric conversion-L band transmission） transmission model of IF signal is widely used in many TV stations. This paper is based on the application of Guizhou Radio and Television Station in the L-band optical transmission system. The function stability, transmission efficiency, redundant backup are main points. This paper introduces the details of signal conversion, transmission design and process monitoring of OE-LB system in detail.
