The strength of silica optical fibers is controlled by flaws, usually on the surface. Such flaws can grow in time so that a silica optical fiber may undergo delayed fracture from the combined influence of low stress levels and the humid environment. This time-dependent phenomenon is often referred to as static fatigue. Assessing the long-term mechanical reliability of silica optical fibers remains a major concern, especially in applications where high reliability is required, such as deep-sea oceanic communication systems and engine
control systems using fiber-optic pressure sensors. In this report, we review briefly a current practice of predicting the conditions under which delayed failure will occur, and elucidate problems in the current predictions. We introduce, furthermore, our unique approach for solving the problems and for understanding static fatigue of silica optical fibers, where we measured directly small-crack growth in silica optical fibers of 125.u m in diameter. |
