有线宽带FTTH场景提速改造方案研究

一方面随着中国移动有线宽带用户发展迅猛,有线宽带端口占用率越来越高,单PON口下带的用户越来越多,难以满足多用户高带宽并发的需求;另一方面随着网络电视、4K、3D视频和游戏等新兴业务的发展,百兆甚至千兆用户需求越来越旺盛,而现有网络不能完全支撑高带宽的业务发展需求,带宽的提速升级迫在眉睫。本文针对中国移动业务旺盛和高价值站点的FTTH接入场景,分析扩容提速需求,提出降低分光比方案和升级10G PON方案,工程实施中应根据实际情况,采用适合的提速改造方案。

Research on Speed - changing Scheme of Fiber to the Home access network

On the one hand, with the rapid of China Mobile cable broadband users, the occupancy rate of wired broadband ports is getting higher and higher, single PON mouth with more and more users, it is difficult to meet the multi-user high-bandwidth concurrent demand; on the other hand with the Internet TV, 4K, 3D and video games and other emerging business development, Fast or even Gigabit users increasingly strong demand, and the existing network can not fully support the high-bandwidth business development needs, bandwidth upgrade speed is imminent. In this paper, we focus on the FTTH access scenarios of China Mobile"s strong and high-value sites, analyze the requirements of speed expansion, propose to reduce the splitting ratio scheme and upgrade the 10G PON scheme. The project should adopt the suitable speed improvement scheme according to the actual situation.
