摘　　要：随着光纤通信技术的突飞猛进和广大用户的宽带视频业务需求日益增长,电信运营商通过大力推广光纤到户(Fibre To The Home,FTTH)接入网拓展高速宽带和交互式网络电视(Internet Protocol Television,IPTV)业务,对广电网络造成了极大的冲击。为了应对这个局面,近几年广电运营商在接入网建设领域一方面保留传统的数字视频广播(Digital Video Broadcast,DVB)网络,另一方面全力建设FTTH,力求实现与电信运营商全面的、差异化竞争。基于此,介绍广电FTTH网络的系统架构、组网方案以及网络设计要点,供广电网络从业人员参考。With the rapid development of fiber optic communication technology and the increasing demand for broadband video services from customers,traditional telecom operators have greatly impacted the broadcasting and television industry by Fibre To The Home(FTTH)access networks to expand high-speed broadband and Internet Protocol Television(IPTV)services.In order to cope with this situation,in recent years,radio and television operators have retained the traditional Digital Video Broadcast(DVB)network in the field of access network construction,and on the other hand,made every effort to build FTTH,striving to achieve comprehensive and differentiated competition with telecommunications operators.This article introduces the system architecture,networking scheme,and network design points of the FTTH network for radio and television industry,providing reference for radio and television network practitioners.
