摘要
介绍了实用化的副载波 ( SC)光纤单芯双向通信的基本方法 ,分析了副载波双向 ( SCD)传输技术与副载波复用 ( SCM)传输技术的主要差别 ,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 ,并给出了指标要求 .
A some basic methods of subcarrier bi directional communication in a single core fiber in practice are introduced in this paper.The technology of subcarrier bi directional communication in a single core fiber is discussed on emphasis.The paper gives the analysis of the mainly different from the technology of subcarrier bi directional communication to subcarrier multiplexed communication.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 subcarrier bi directional communication technology in a single fiber are given.
