我们从光纤损耗测量的物理机理出发,对影响多模光纤损耗测量精度的各种因素进行了详细的分析,建立了各误差与总测量误差关系间的方程式,并对最近结束的全国多模光纤损耗测量比对的数据进行分析,从而第一次得出了影响测量精度的各误差因素与总的测量误差之间的定量关系。我们认为可以从三方面进一步提高多模光纤损耗测量的精度。
Based on the physical mechanism of optical fiber loss measurement, we analyzed in detail the various factors affecting the measurement accuracy of multimode optical fiber loss, established the equations between the errors and the total measurement error, and analyzed the recently concluded national multimode optical fiber The data of loss measurement and comparison are analyzed, and for the first time, the quantitative relationship between the error factors and the total measurement error that affect the measurement accuracy is obtained. We think it is possible to further improve the accuracy of multimode fiber loss measurement from three aspects.
