摘要
随着有线数字电视在红河州越来越普及,其系统抗干扰能力强而备受欢迎。但近一段时间来,红河州各市县地面数字无线发射区域内对有线数字电视产生较强的干扰,导致数字电视故障频发。介绍了红河地区解决地面数字无线发射区域干扰的办法,在强射频干扰下应对HFC(Hybrid Fiber-Coaxial)混合光纤同轴电缆网的改造、维护工作,同时列举了彻底解决有线数字电视射频干扰问题的具体办法。
With the increasing popularity of cable digital television in Honghe Prefecture,this system with the strong anti-interference ability has become very popular. However,in recent years,in Honghe cities and counties,the terrestrial digital wireless transmission area has a strong interference on the cable digital television,leading to frequent digital TV failure. This article introduces the method of resolving the terrestrial digital wireless transmitting area interference in Honghe area and guiding the reconstruction and maintenance work of HFC（ Hybrid Fiber-Coaxial） hybrid optical fiber coaxial cable network under the strong radio frequency interference. Meanwhile,it gives specific examples of solving the problem of radio frequency interference of cable digital television.
