浅谈河北地球站上行机房信源系统选配

文章介绍了微波通信和光纤通信的基本原理。根据其特点和微波首站光缆和微波互为备份的传输方式,卫星地球站合理配置信号源,光纤为主,微波为辅,以垫播系统信号作为应急播出。经过比较选择,采用科迪切换器实现信号源故障自动切换,以及使用跳线排来实现信号源到调制器应急跨接。卫星地球站采用这样的信源系统配置,可保证节目安全优质播出。

Discussion on Hebei earth station source system selection

This paper introduces the basic principles of microwave communication and optical fiber communications.According to the characteristics and microwave station cable and microwave mutual backup transmission mode,rational allocation of the satellite earth station signal source,optical fiber based,microwave assisted,to pad broadcast system signal as an emergency broadcast.After comparison and selection,the Kedi switcher realization of automatic signal source fault switching.,and the use of jumper line to achieve the signal source to the modulator emergency across.Satellite earth station using this source system configuration,ensure the safety and high quality broadcast programs.
