摘要

光纤的可靠性是保证光网络寿命的关键

可靠性由光纤的强度分布和疲劳行为共同决定。应用光纤的强度分布数据和蒙特卡洛方法

分析了筛选强度、应力腐蚀敏感性参数和载荷水平等因素对光纤可靠性的影响。分析结果表明

筛选强度的提高可改善筛选后光纤的强度分布

但同时会导致部分筛选后光纤的强度明显降低;按照基于幂定律理论的光纤疲劳行为模型

应力腐蚀敏感性参数的提高和光纤受到静载荷水平的降低可以提高光纤的理论寿命。

Abstract

The reliability of optical fibers is the key to ensuring the service life of optical communication networks

which is determined by both their strength distributions and their fatigue behaviors.In this paper

the effects of such factors as screening intensity

stress corrosion susceptibility parameters and load level on fiber reliability are analyzed by using the fiber strength distribution data and the Monte Carlo method.The analytical results indicate that while the increase of the screening intensity can improve the screened fiber strength distribution

it may result in the obvious decrease of parts of the screened fiber strength.In line with the power law theory-based fiber fatigue behavior model

the theoretical lifetime of fibers can be increased with the increase of the stress corrosion susceptibility parameters and the decrease of static load level on the fibers.
