摘要
基于有线电视网络有线无线融合覆盖的智慧社区建设,主要是充分利用现有有线电视HFC网络光纤资源,在不增加敷设主干光缆的前提下,采用无源光网络技术快速将社区内住宅、商铺、办公场所等进行光纤到桌面的全光网络覆盖,社区公共区域采用Cable WiFi进行无线无缝覆盖。应用C-DOCSIS技术,实现有线电视同轴电缆分配网的无源分配网络升级改造,通过同轴电缆的过电能力,实现社区Cable WiFi集中供电及无源覆盖,实现无源光网络、无源同轴网络、无源Cable WiFi网络的同步融合覆盖,在承载高标清直播电视、交互电视、宽带等传统业务基础上,实现社区视频监控、门禁、车联网、物联网、政务网、党员远程教育网等智慧社区业务的承载。
The construction of smart community based on cable network and wireless convergence coverage is mainly to make full use of the existing cable TV HFC network fiber resources,adopt passive optical network technology to rapidly achieve the all optical fiber-to-desktop network coverage for residential houses,shops,and offices in the community without increasing the laying of trunk optical cables,and realize the wireless seamless coverage through Cable WiFi in public areas. By using C-DOCSIS technology,the passive distribution network of CATV coaxial cable distribution network is upgraded and transformed. The community Cable WiFi centralized power supply and passive coverage are realized through the overcurrent ability of the coaxial cable. The synchronous convergence coverage of passive optical network,passive coaxial network and passive Cable WiFi network is realized. On the basis of carrying high-standard live TV,interactive television,broadband and other traditional services,the smart community networking scheme can also provide the services of the community video surveillance,access control,car networking,Internet of things,government affairs network,party members,undefined distance education network and other intelligent community.
