摘要
针对WDM-PON断点检测中亟需解决的支路多、节点密问题,为实现高精度定位各支路的断点提出了一种基于宽带混沌光激光器的检测方法。在分析宽带混沌源的特性的基础上,进行了初步的仿真实验,结果表明该方法可以高精度定位WDM-PON支路中断点的位置,空间分辨率达到7cm且与探测距离无关。
Break detection for WDM-PON needed to solve the multi-branch,node density problem for the real- ization of high-precision positioning of each branch proposed a breakpoint detection method based broadband chaotic light lasers. On the basis of analyzing the characteristics of broadband chaotic sources on a prelimi- nary simulation results show that this method can be highly accurate positioning WDM-PON branch break- point location, spatial resolution of 7cm and independent of the detection distance.
