Paper Abstract

Weibull analysis of tensile strength data is routinely performed to determine the quality of optical fiber. A typical Weibull analysis includes setting up an experiment, testing the samples, plotting and interpreting the data, and performing a statistical analysis. One typical plot that is often included in the analysis is the Weibull probability plot in which the data are plotted as points on a special type of graph paper known as Weibull probability paper. If the data belong to a Weibull probability density function, they will fall approximately on a straight line. A search of the literature reveals that many Weibull analyses have been performed on optical fiber, but the associated Weibull probability plots have been drawn incorrectly. In some instances the plots have been shown with the ordinate (Probability) starting from 0% and ending at 100%. This has no physical meaning because the Weibull probability density function is a continuous distribution and is inherently not bounded. This paper will discuss the Weibull probability density function, the proper construction of Weibull probability graph paper, and interpretation of data through analysis of the associated probability plot.
