Abstract

Methods for predicting service reliability of passive fiber optic interconnections have not developed to the same extent as they have for fiber. Much progress has been made in the understanding of failure modes, however, it has not been extended to the estimation of mean life or failure rate as a function of time. The most critical need is the development of appropriate life-stress models which include test acceleration factors and statistical analysis methods. In this paper, simple models are proposed for three distinct failure modes: (1) flexural fatigue of a connector bend limiting assembly, (2) static fatigue of a ceramic connector alignment sleeve, and (3) torsional fatigue of fibers in splices. The more general problem is discussed in the context of these examples.
