摘　　要：随着超高清、增强现实/虚拟现实和千兆宽带接入进入千家万户,原有的混合光纤同轴电缆(Hybrid Fiber Coax,HFC)有线电视网络已不能有效承载各类新兴业务。同时,原有网络在运营维护、设备功耗、安全传输等方面与光纤到户(Fibre To The Home,FTTH)网络相比,存在一定劣势,因此,将原HFC网络升级改造为FTTH网络是必然趋势。基于此,以曲靖市麒麟区城区有线电视FTTH网络升级改造项目为例,对有线电视FTTH网络升级改造的规划建设、安全管理以及后续运营维护等方面进行探讨。With ultra-high definition, augmented reality/virtual reality and gigabit broadband access entering millions of households,the original Hybrid Fiber Coax(HFC) cable TV network can no longer effectively carry all kinds of emerging services. At the same time, the original network has certain disadvantages compared with Fibre To The Home(FTTH) network in terms of operation and maintenance, equipment power consumption, security transmission, etc. It is an inevitable trend to upgrade the original HFC network to FTTH network. Taking the urban cable TV FTTH network upgrading project in Qilin district of Qujing city as an example, this paper discusses the planning and construction, security management and subsequent operation and maintenance of cable TV FTTH network upgrading project.
