摘　　要：介绍了实用化的单芯双向通信的基本方法 ,分析了波分复用 ( WDM)单芯双向通信方式并给出了指标要求。重点讨论了副载波 ( SC)单芯双向传输技术 ,通过在电域采用频分制技术解决自发自收问题 ,确定了方向滤波器技术指标。最后给出了采用副载波技术所实现的单芯双向传输系统的性能。Some basic methods of bidirectional communication in a single fiber in practice are introduced in this paper. The way of wavelength division multiplexing bidirectional communication is analyzed and the performances desired are given. The technology of sub carrier bidirectional communication. in a single fiber is discussed on emphasis. The problem of self transmitting and self receiving is resolved by frequency division technology in electrical field. On this basis, the performance of directional filter is determined. At last, the performances of a realized system with sub carrier bidirectional communication. technology in a single fiber are given.
