Research on Elimination Technology of Massive Redundant Interference Information in Optical Network

针对光纤网络中冗余干扰信息进行研究,采用传统排除技术只针对特殊干扰区域回波情况进行分析,导致排除精准度较低,因此,提出了光纤网络中海量冗余干扰信息排除技术研究。依据光纤网络回波数据,计算回波强度差,判断冗余干扰信息方位。根据定位结果,设计信息排除工作流程,从流程中获取异于常态信息,并进行逻辑诊断。利用功率法对网络接收功率进行处理,根据径向干扰去除模型,获取光纤网络衰减方程,并对特殊干扰区域和混合区域回波功率进行计算,获取真实回波功率值,由此实现冗余干扰信息的排除。由实验对比结果可知,该技术最高排除精准度可达到90%,为后续光纤网络干扰问题研究提供有效支持。

In order to study the redundant interference information in the optical network,the traditional elimination technology is only used to analyze the echo situation of the special interference area,resulting in low accuracy.Therefore,the research on the elimination technology of massive redundant interference information in the optical network is proposed.According to the echo data of the optical network,the echo intensity difference is calculated,and the orientation of the redundant interference information is judged.According to the positioning result,the design information excludes the workflow,obtains the normal information from the process,and performs logical diagnosis.The power method is used to process the received power of the network.According to the radial interference removal model,the attenuation equation of the fiber network is obtained,and the echo power of the special interference region and the mixed region is calculated to obtain the true echo power value,thereby achieving redundant interference.Exclusion of information.It can be seen from the experimental comparison results that the highest exclusion accuracy of the technology can reach 90%,which provides effective support for the study of subsequent fiber network interference problems.
