家宽提速背景下的XG-PON改造方案研究

Research on optimization scheme of wired access network under the background of broadband speed-up

随着'提速降费'的持续推进及4K/8K等新业务的出现,中国移动有线宽带用户的签约带宽由过去的10 Mbit/s提升到100 Mbit/s以上,部分区域实现1 000 Mbit/s接入能力,用户规模也突破了1.3亿。用户规模的激增、业务带宽需求的不断提升将对现有的有线宽带网络带来极大挑战。结合中国移动有线宽带网络现状,分析扩容、提速需求,提出不同场景下有线接入网改造方案,为后期有线接入网的改造及演进提供了重要的指导作用。

With the continuous promotion of the speed-up ensures and the emergence of 4 K/8 K new services,bandwidth demands of subscriber has increased from 10 Mbit/s to more than 1 000 Mbit/s.And the user scale has also exceeded 130 million.The rapid growth of users and the increasing demand for bandwidth will bring great challenges to the existing wired broadband networks.Based on the current situation of the wired broadband network,the demand for capacity expansion and speed-up was analyzed,and different scenarios of wired access network optimization scheme were puts forward,which provided an important guidance for the later wired access network evolution.
