摘要
分别介绍采用分布反馈型(DFB)激光器和外调制YAG激光器的残留边带VSB-AM多路电视信号传输光端机的工作原理及其性能,并在理论上对光纤系统的性能进行了分析与比较。另外,对于光纤技术在有线电视传输网络设计中的应用形式也作了分析与说明。
The principles and performances of optical fiber terminals
for transmission of multi-channel VSBAM TV signal,employing distributed
feedback(DFB) laser ard external modulated YAG laser,are intrnduced
respectively.The performances of the optical fiber system are analyzed and
compared theoretically.Also,the modes of opplication of optical fiber
technique to the design of transmission network of cable TV are analyzed
and described.
