在光纤传输网络环境中,为将传输信号的衰耗周期控制在既定数值范围之内,实现对光应用信号的最大化应用,提出光纤传输网络中的衰耗节点定位方法。联合激光器驱动电路与波分复用分路器,确定与光纤传输信号相关的调制编码形式,实现光纤传输网络的构建。在此基础上,确定衰耗信号的相似性数值,通过定义信号结构体相关函数的方式,确定局部衰耗定位点的实际所处位置,完成光纤传输网络中衰耗节点定位方法研究。实验结果表明,所提方法的数据传输信噪比最高值仅为50 dB,衰耗周期数值最高为3.03 mm,在光纤传输网络环境中更符合光应用信号的最大化应用需求。

In the environment of optical fiber transmission network,in order to control the attenuation period of transmission signal within the given value range and realize the maximum application of optical application signal,a method of attenuation node location in optical fiber transmission network is proposed.Combining the laser driving circuit and WDM splitter,the modulation and coding form related to the optical fiber transmission signal is determined,and the construction of optical fiber transmission network is realized.On this basis,determine the similarity value of the attenuation signal,determine the actual location of the local attenuation location point by defining the correlation function of the signal structure,and complete the research on the attenuation node location method in the optical fiber transmission network.The experimental results show that the maximum signal-to-noise ratio of data transmission of the proposed method is only 50 dB and the maximum attenuation period is 3.03 mm,which is more in line with the maximum application requirements of optical application signals in the environment of optical fiber transmission network.
