1工程背量随着Internet的持续快速发展,各类互联网互动业务如视频会议、实时游戏、IPTV等应用不断涌现,使得人们对网络接入带宽提出了更高的要求。现有铜线接入技术难以满足这样的高带宽需求,于是能够轻松提供1000Mb/s带宽的FTTH成为实现这些业务的最佳手段。当前,受市场、业务、技术、成本、竞争多方面的驱动,国内运营商对FTTH的兴趣
1 Engineering Back-up With the continuous and rapid development of the Internet, various Internet interactive services such as video conferencing, real-time games, IPTV applications continue to emerge, making people put forward higher requirements on network access bandwidth. Existing copper access technologies can not meet such high bandwidth demands, so FTTH, which offers 1000Mb / s bandwidth with ease, is the best way to implement these services. At present, driven by the multi-faceted market, business, technology, cost and competition, domestic operators’ interest in FTTH
