摘要
FTTH是以光纤为传输媒介的宽带接入方式,光纤通信具有频带宽、容量大、单位带宽成本低、可承载高质量视频、绿色环保等特点,它的使用可以在接入环节更好地适应融合性业务发展需要。本文分析FTTH的建网优势,并结合新建和改造两种场景详细介绍ODN的设计方法。
FTTH is the broadband access method that takes optic fiber as transmission medium. Optic fiber communication has the features of frequency bandwidth, large capacity, low cost per unit bandwidth, arrying high-quality video and environmental protection. Its use can be better adapted to the integration of business development in access links. This paper analyzes the advantages of network construction based on FTTH and introduces the ODN design methods based on the two scenarios which are new and improved.
