在国家三网融合的大背景下,广电运营商和电信运营商在各自的基础网络上大力发展高性能的宽带接入网,广电运营商采用PON+EOC和CMTS接入方式,电信运营商是ADSL和FTTX,两者的最终目标都是光纤到户。由于电信早已在接入网建设方面积累了极为丰富的经验,广电在接入网方面落后于电信,因此广电运营商在网络改造和建设方面必须选好先进的技术和方案才能做大做强基础网络。在接入技术方面,前几年由于基于同轴电缆通信的技术比较多,再加上在频段的选择上可以选用低频方案和高频方案,因此很多广电运营商都很难选择采用哪种EOC接入技术。2010年年底,广电总局发布《有线电视 In the context of the national triple play, radio and television operators and telecom operators are making great efforts to develop high-performance broadband access networks on their respective basic networks. Radio and television operators adopt PON + EOC and CMTS access methods, and telecom operators are ADSL and FTTX, the ultimate goal of both are FTTH. Since telecommunications has long accumulated rich experience in access network construction, radio and television lag behind telecommunications in terms of access networks. Therefore, radio and television operators must choose advanced technologies and solutions to make their networks bigger and stronger based on network transformation and construction The internet. In access technology, a few years ago due to more technology based on coaxial cable communication, coupled with the choice of the band can choose low-frequency and high-frequency programs, so many radio and television operators are difficult to choose which EOC access Into the technology. The end of 2010, SARFT released "Cable TV
