摘要
利用邮电系统现有的光纤网络系统，加上双向传输技术，开放多媒体等宽带业务，是今后信息传输的必然趋势。它是信息高速公路的基本框架，受到越来越多人的关注，本文介绍了光纤电视的双向传输技术，并讨论了系统的设计方法。
To open the two-way CATV and other wide-band services in the existing optical fibre network of the telecommunication system is an inexorable trend for information transmission and is the basic framework of the 'information express-way'.It is concerned by more and more people.The two-way transmission technique of CATV by optical fibre is introduced and the design of the system is discussed.
