本文就福建省永春县HFC网络的实际情况,对该县的HFC网络升级改造提出了可行性方案。认为在目前的网络升级改造中应尽量使用光接收机直接覆盖用户,每个光节点覆盖用户200～500户;单元用户采用集中分配接入方式,以减少信号串接点、故障率及运维成本,使网络及工程设计工作变得简单,并为以后双向回传等业务的开展奠定了良好的基础。
In this paper, the actual situation of HFC network in Yongchun County, Fujian Province, the HFC network upgrade in the county proposed a viable program. It is considered that optical receivers should be used to cover users directly in the current network upgrading and reconstruction. Each optical node covers 200 to 500 subscribers. Unit subscribers use centralized distribution access to reduce the number of signal connections, failure rates and operation and maintenance costs , Made the network and engineering design simple and laid a good foundation for the future two-way return business.
