HFC同轴接入网继续前行的思路转变

Discussion on HFC Coax Access Network Continue to Change of the Thinking Ahead

随着我国经济的不断发展,科技水平的不断进步,有线电视的发展也在不断加速,尤其光网的延伸,不少地方已经做到FTTH。HFC同轴接入网似乎要退出历史的舞台,但介于各地经济水平所限,各地发展并不均衡,目前的网络还有相当一部分是HFC网络,在没有全部改成光网之前,原来的HFC同轴接入网不但要继续前行,还得承载更多的新业务,这就需要同轴接入网在技术设计、施工和维护等环节有所突破来适应日新月异的网络形式,主要阐述了HFC同轴接入网发展的思考。

With the continuous development of our economy,the development of science and technology,the development of cable TV is also in constant speed,especially optical network extension,many places have done FTTH. HFC coaxaccess network seems to withdraw from the stage of history,but the economiclevel around between limit,around the development is not balanced,the current network there is a considerable part of the HFC network,before has not changed all optical access network,HFC coaxial original not only to continue to move forward,also carrying more new business. This need to coax access networktechnology in design,construction and maintenance and other links to adapt the network forms a breakthrough change rapidly. This paper mainly expounds thethinking of development of coax access network HFC.
