摘　　要：构建符合技术发展趋势的有线电视接入网络是多业务承载的基础,针对HFC双向接入网络和FTTH全光网络两网并存的现状,按照整体规划、分步实施的原则,结合在用网络的实际及用户的业务接入需求,利用光节点预留的主干光缆资源,基于光节点以下电缆接入网络的结构,按照全光网络覆盖规划方案敷设每个楼栋单元的接入光缆,从而逐步推进HFC双向接入网络过渡到全光网络。Building a cable TV access network that conforms to the technological development trend is the basis for multi-service bearing.In view of the coexistence of the HFC bidirectional access network and the FTTH all-optical network,according to the principles of overall planning and step-by-step implementation,combined with the network in use.According to the actual and user s business access requirements,the backbone optical cable resources reserved by the optical node are used,and the access optical cable of each building unit is laid according to the all-optical network coverage plan based on the structure of the cable access network below the optical node,so as to gradually promote the HFC bidirectional access network transitions to an all-optical network.
