| 摘 要： | 在光纤损耗测量中,由光源谱宽产生的误差是影响测量精度的一个重要因素.本文从基本的物理概念出发,证明了光纤谱损耗是影响该误差的主要因素.根据误差修正公式计算了这类误差的大小,给出了一组适合1300nmLED的典型误差修正曲线,利用该曲线可方便地消除大部分由光源谱宽产生的误差.

| Abstract: | In optical fiber loss measurements errors are inevitably producedwhile using a light source with wide spectral line-width,espcially at longwavelengths.This paper,reveals the major factor producing the errors whichare calculated by formuls.A typical modication curve is given for LED at1300nm wavelength and by using the curve we can easily eliminate the gre-ater part of the errors. |
