10G EPON产业链发展情况

传统铜缆线作为传输介质的信道带宽有限,基于铜线介质的xDSL技术在国内已非接入网建设的主要技术,取而代之的是以EPON和GPON为代表的无源光接入技术。目前,国内运营商EPON,GPON均已实现商用部署,尤其是EPON目前在国内已突破2000多万线的建设规模。考虑到未来IPHDTV和富媒体通信等新业务对网络接入带宽的成倍数增长需求,10GEPON作为EPON的后续演进技术,受到了业界的广泛关注。

The Development of 10G EPON Industry Chain

As a result of the naturally limited channel bandwidth of copper wire,passive optical network(PON),such as EPON and GPON,is used as the major access network development scheme instead of traditional xDSL.The commercial development of EPON and GPON has been disposed on a large scale by native carrier,especially which the number of development of EPON has exceeded 20 million lines.With the bandwidth requirement increase of new business,such as rich media communication,IPHDTV and so on,10G EPON attracts broad ...
