摘　　要："光进铜退"已经成为近年来的热议,从电信延伸至广电行业。光纤被认为是迄今为止最优的传输媒质,被各运营商利用来突破接入带宽"瓶颈"。广电是否需要抛弃同轴网部署FTTH,也引起了业内的热议。随着大数据时代的来临,以往的数据传输速率已无法满足用户需求,广电网络急需寻求新的突破与变革,对于HFC网络的部署需要更进一步的思考和实践。本文针对有线电视网络采用FTTB+C-DOCSIS无源同轴接入网方式的网络部署进行探讨,为广电网络提供更加丰富可靠的参考与解决方案。In recent years , Optical Cable Deploys and Coaxial Cable Retreats has become a hot theme in fields from telecommunications to radio and television industry.Optical fiber is considered by far the most optimal transmission medium. Various operators use it to break through the ＂bottleneck＂ of access bandwidth. With the coming of the era of big data, previous data transfer rates have been unable to meet the demand of users, radio and television networks need to seek new breakthroughs and change.It is needed to think or practice further for HFC network deployment. The FTTB ＋ C - passive coaxial access network deployment were discussed.For radio and television networks it provides more reliable solution.
