The Fiber-network Design of Fenghua TV Two-way Recontruction

双向网络改造既要有发展,也要有继承。每一次的网改要充分利用原有的网络资源,要满足目前的需要,也要预留未来网络发展的空间。在原有的HFC网基础上经过最小的改造,升级为FTTB;在目前的FTTB上如何建设自愈环网,并最终升级为FTTH。

CATV network two- way recontruction since have to have a development as well as have been already inherited. Every network reconstruction wants to make use of original network resources, Want to satisfy a current demand, and want to reserve the space of the network development in future. On the original HFC network, by the minimum reconstruction get stripe to FTTB ; On current FTTB How to construct Self - Healing Ring network, and finally get stripe to FTTH.
