光纤接入中如何解决ODN管理难题

文章来源:ICCSZ

2011年1月20日消息,在FTTx发展中,接入层需要新建一张巨大的光纤分配网络,即ODN网络。ODN网络建设成本高昂,最高可占总体投资的50%-70%,是FTTx投资的重点。同时,ODN也是FTTx管理的难点。首先它相比铜线简单的P2P结构,ODN多采用P2MP拓扑,网络中的接续节点多,网络管理复杂。其次,光纤比铜线敏感,更容易受损。

  因此,对ODN进行高效的建设、运营和维护至关重要,需要一套智能、准确的管理解决方案,确保ODN网络得到充分利用,有效保护长期投资。目前,如何对ODN网络进行科学的管理已经成为各大运营商和ITU-T等标准组织关注的焦点。

  那么能否在不改变ODN的无源特性下,解决ODN管理的两大核心问题,实现ODN的自动化管理呢?华为提出了iODN(智能ODN)解决方案。在iODN解决方案中,ODN产品新增了以下智能特性:光纤标识管理、端口状态收集、端口查找指示、可视化工具PDA等。

  iODN解决方案可以实现ODN光纤连接信息的自动录入和管理,保证存量系统信息的准确无误和及时同步。同时,通过PDA的可视化软件及iODN设备上的智能LED指示,可以实现光纤自动化查找、精确操作,极大提高运维效率,实现ODN网络的高效运营和维护。此外,基于iODN架构,在存量系统基础上可以开发出多种增值应用,实现施工、运维全流程自动化。
