摘　　要：随着业务需求的增长,要求网络带宽越来越宽。有线电视HFC网络正在急速演变,其同轴电缆部分将逐步缩短,使其有利于语音、数据和视频信息的综合传输。交互电视、VOD、IP应用正在被人们看好,为实现用户的高比特率双向传送,HFC网络必须改造成光纤到大楼、光纤到家庭的结构。Nowadays the increasing requirements of services demands a broader network bandwidth . Cable TV network based on HFC is changing fast. The coaxial cable will be shortened gradually, and it will be advantageous to synthesize the transfers of voice, data and video. The interactive TV, VOD, IP application is being accepted by many people. So in order to carry out the high bit bidirectional transmission, optical fiber to multi-storied building and optical fiber to house must be realized.
