摘要
本文叙述SWFM-IM彩色电视双伴音光纤传输系统的基本原理和主要性能。该传输系统可以在一根光纤上同时传输1路彩色电视视频信号和2路伴音信号或数字信号,具有接收灵敏度高、传输距离长、失真小的特点,且能满足传输立体声的质量要求。
This paper describes the basic principle and main performance of the SWFM-IM(square wave frequency modulation-intensity modulation) optical fiber transmission system with two accompanying sound channels for colour TV programs. The transmission system may transmit one colour TV video signal and two sound signal or data signal on a optical fiber at the same time. It has the advantage of high receiver sensitivity, long transmission distance and minimum distortion. It can also satisfy the quality requirement of transmiting stereo.
