Paper Abstract

There are 3 popular methods for measuring of optical fiber attenuation i.e. cut-back, backscattering and insertion loss. In field applications the last two methods are frequently used in spite of the best accuracy of the first one. The backscattering has a disadvantage of limited dynamic range in comparison with the other two, but is very easy to apply. For the whole long link attenuation measurements the insertion loss method is in popular use. It's main drawback is an error resulting from unknown connector loss. This paper presents an explanation of all these methods with error analysis as well as field tested modification of the insertion loss method aimed to eliminate errors caused by connector loss.
