Abstract: Method and apparatus wherein continuous indexed lengths of optical fiber are automatically measured for load at failure for each failure below a predetermined maximum stress. A predetermined length of optical fiber is indexed. The optical fiber is clamped at one or more clamp points along its length. Increasing tension is applied to a first indexed length of optical fiber between at least one clamp point and a tension application means. Increasing tension is applied between an initial value and the predetermined maximum load. The increasing tension is measured during its application. If failure occurs, the actual load at failure is detected while the increasing tension is being applied. When failure does not occur, the first length of optical fiber is released and a second length of optical fiber is indexed to the position where increasing tension is applied to the second length between at least one clamp point and the tension application means.
