本文介绍了由全国十一个单位参加的多模光纤长、短波长损耗测量比对。比对结果的平均标准偏差为:1)短波长:单位损耗偏差0.11dB/km,总损耗偏差0.27dB;2)长波长:单位损耗偏差0.11dB/km,总损耗偏差0.27 dB。
This paper introduces the comparison of long and short wavelength loss measurement of multimode optical fiber which is participated by eleven units nationwide. The average standard deviation of the alignment results is: 1) short wavelength: unit loss deviation 0.11dB / km, total loss deviation 0.27dB; 2) long wavelength: unit loss deviation 0.11dB / km, total loss deviation 0.27dB.
