摘要
研究了 WDM光网络节点的组成结构 ,光联网是通过可重构的选路节点建立端到端的“虚波长”通道来实现源和目的之间端到端的光路连接的 ,而波长变换器又是实现虚波长通道的根本途径。在介绍了几种波长转换器结构的基础上 ,着重对比研究了波长转换技术对光网络组网的灵活性、节点操作的复杂性方面的影响。可见使用波长转换技术能充分利用有限的波长资源 ,提高波长重用效率 。
In this paper,had studied the configuration of o ptical networking nodes,a end-to-end virtual wavelength path established by r eco nfigurable routing nodes to achieve optical networking of optical channel trails between access points,in this process wavelength converter is the key to realiz e visual wavelength path.On the basis of introducing some of the present all-op t ical wavelength converter,highlight researched wavelength converter effect on th e network's flexible and node's operation complexity.In conclusion,using wavelen gth converter can efficiently utilize finite wavelength resource,improve wavelen gth-reusing efficiency and reduce network congestion ratio.
