Abstract
Fracture of fiber in a connector occurs when induced tensile stress exceeds local strength, usually governed by a stripping-related flaw. Stress analyses based upon elementary models from structural mechanics are presented to explore the significance of differential thermal expansion of ferrule and backbone. Results of finite-element analyses are used to suggest an epoxy-driven mechanism for fractures observed after thermal cycling. Implications for reliability are discussed.
