有线电视光纤传输系统江尤目前，有线电视网络中几乎都是采用传统的同轴电缆作为传输手段，但存在着一定的问题。（１）电缆干线传输每百米须设置一个放大器，而多级放大器的级联除带来噪声积累外，还伴随交调、互调失真的增加，致使终端处较难保证收看质量。（２）电缆的...
Cable television fiber transmission system Jiang You At present, almost all of the cable television networks using traditional coaxial cable as a means of transmission, but there are some problems. (1) An amplifier must be set up for every 100 meters of cable trunk transmission. The cascade of multistage amplifiers not only brings noise accumulation, but also increases the intermodulation and intermodulation distortion, which makes it difficult for terminals to guarantee the quality of viewing. (2) cable ...
