PON监控系统中的布里渊散射分析

摘要

The paper describes without affecting the quality of the transmission signal,distinguish Brillouin frequency shift between different branch optical fibers through the optical fiber doped,and then determine the link status of each of the branching optical fibers,analysis scattering spectrum by BOTDR and locate problem fibre.The Brillouin frequency shift and identifiable fibers are made in detail.%主要介绍了在不影响传输信号质量的同时,通过对光纤掺杂区得到分支光纤不同的布里渊频移,进而判断各分支光纤的链路状态,再通过BOTDR来分析布里渊散射频谱,对问题光纤进行定位.文中对布里渊频移和可识别光纤做出了详细的阐述.
