FTTN

At present , FTTH / FTTN is at the stage of small-scale test and trial commercial operation .

目前FTTH/FTTN在我国正处于小规模试验和试商用阶段。

As well as FTTP and FTTN , there are other ways for telecoms operators to get into the television market .

除了FTTP和FTTN，电信运营商进入电视市场还有其它的路子。

At the same time compared FTTH , FTTB , FTTN three modes , select the main building FTTB mode . 2 .

同时对比了FTTH、FTTB、FTTN三种模式，选取FTTB为主要建设模式。

The main technology FTTH / FTTN now adopts is E / GPON , but it will adopt larger-capacity optical access technology in the future .

FTTN目前采用的主要技术为E/GPON，但未来将会采用更大容量的光接入技术。

Finally , the EPON network design and planning are studied and discussed in this thesis . Based on the analysis and comparison of the three engineering examples , the applying scene and engineering effect of FTTN , FTTB and FTTH in actual construction are summarized .

最后本文研究讨论了EPON网络的设计与规划，并在此基础上分析比较了三个工程案例，总结了FTTN、FTTB和FTTH三种方式在实际建设中的适用场景和工程效果。
