随着通信技术日新月异的发展,人们对网络的需求越来越大,这种需求需要高速的、高带宽的网络来支撑,GPON是目前实现光纤到户的最佳选择。本文从在网络设计的角度出发,针对设计环节存在的一些问题,通过对FTTH光缆网络结构、FTTH光缆网络现实结构以及对GPON网络的ODN一级分光结构、二级分光结构的分析,分别测算了不同场景下采用1:32和1:64的GPON网络的传输距离,对不同结构的应用进行了对比分析。指出了不同ODN结构适合的不同场景,提出了FTTH网络中的光缆线路设计方法。
With the rapid development of communication technology, the demand for the network is getting larger and larger. This demand needs high-speed, high-bandwidth network to support. GPON is the best choice for realizing FTTH at present. This article from the network design point of view, for the design of some of the problems exist, through the FTTH fiber optic cable network structure, FTTH optical cable network and the actual structure of the GPON network ODN first-class structure, the second-class structure of the analysis were calculated Different scenarios using the transmission distance of 1:32 and 1:64 GPON networks, the application of different structures were compared. Different scenarios suitable for different ODN structures are pointed out, and the design method of fiber optic cable in FTTH network is proposed.
