有线电视双向网接入技术选择

EPON技术因其高带宽、无源分配、易维护、支持多业务等优势,近年来正在成为宽带接入的主要技术之一,也非常适合于有线电视网络开展双向数据业务。在接入技术方面有EoC、LAN,部分广电有线电视网络已经进行了基于Cable Modem方式的HFC双向网改造,那么如何选择宽带接入方式呢？对HFC、EPON以及几种接入技术做技术分析、投入成本分析以及网络现状分析,以此选择适合有线电视网宽带接入的技术方式。

Two- Way CATV Network Access Technology Selection

In recently years,due to many advantages including high bandwidth,passive distribution,easy to maintain,support multi-service and etc,EPON technology has become one of the main technology of broadband access,and is very suitable to develop two-way data services on（over） CATV network.In network access technology,there are EoC,LAN and so on.Some CATV network had been carried out based on two-way cable modem HFC network reconstruction methods,how to choose the way of broadband access？ Based on the EoC,EPON,and some access technology,this article does some technical,investment cost,network status analysis,and selects the appropriate broadband access methods for CATV network.
