交接配线式ODN结构的研究

Research on Cross-Connecting Distribution Line Type of ODN Structure

针对光纤到户(FTTH:Fiber To The Home)网络建设中,在接入用户不确定条件下的配线结构选择问题,通过定性和定量的分析方法,对直接配线式ODN(Optical Distribution Network)结构与交接配线式ODN结构进行比较。结果表明,交接配线式ODN结构具有接入稳定、覆盖范围大和扩容灵活的优点,适宜在竞争的电信市场环境中应用,对FTTH的大规模工程建设具有一定的借鉴意义。

In order to solve the problem in choosing wining structure of building the FTTH （Fiber To The Home）network under the uncertain conditions of access users,we use qualitative and quantitative analysis methods to compare cross-connecting distribution line type of ODN （Optical Distribution Network） structure and direct connecting distribution line ble access ability and a wide covering ability and a flexi application in the competitive telecommunication mark scale construction projects on the FTTH network. type of ODN structure, find out that it has a stable expansion ability,so that is appropriate for the et,has certain reference significance during largescale construction projects on the FTTH network.
