FTTH是以光纤为传输媒质的宽带接入方式,具有高带宽、抗干扰、易维护等特点,是目前已有的固定接入技术中最能满足面向未来需求的技术,是光纤宽带网络的终极模式。从FTTH应用场景、FTTH与FTTB的技术对比及建设成本方面进行分析,提出FTTH规模应用条件已经成熟,并就PON技术选择、分光比、后续演进方向等方面提出建设建议。
FTTH is a broadband access method using optical fiber as a transmission medium and has the characteristics of high bandwidth, interference rejection and easy maintenance, and is currently the technology that can best meet the future requirements of fixed access technologies and is the ultimate of optical fiber broadband networks mode. From the FTTH application scenario, the technical comparison between FTTH and FTTB and the construction cost analysis, the application conditions of FTTH scale have been put forward, and suggestions for construction of PON technology selection, splitting ratio and subsequent evolution direction are put forward.
