A new method of precise measurement of optical fiber attenuation
摘要
在分析了光纤的衰减现有的三种测试方法的基础上
提出了一种新的测量方法
此方法消除了由测量方法设计而带来的光纤链路总衰减测量误差
极大地提高了测试精确度 .
Abstract
Based on an analysis of three current methods of measur ement of optical fiber attenuation
we proposed a new measuring method which can completely eliminate the measurement error of overall attenuation in optical fi ber link caused by existing methods
this greatly enhancing the measuring accura cy.
