AI Technical Summary
Existing technologies lack methods for reliability assessment and lifetime prediction of hollow-to-solid fiber optic connections, resulting in assessment results that lack scientific basis and have significant biases, making it difficult to meet actual engineering needs.
A failure physics model incorporating multiple stress coupling effects, including temperature, humidity, and vibration acceleration, is established. Performance parameters are obtained through accelerated aging tests, and the failure physics model is constructed. Actual stress influence parameters are calculated, and insertion loss, return loss, and polarization-dependent loss are evaluated. Reliability test results are generated, and remaining service life is predicted.
It enables accurate reliability assessment and lifetime prediction of hollow-to-solid fiber optic connections, reduces maintenance costs, and supports the large-scale deployment of hollow-core optical fibers in high-end scenarios such as long-distance optical transmission, high-power optical transmission, and quantum communication.
