光纤受外部影响时的老化与损坏过程研究成果,目前引起了光缆通信专家们的很大兴趣。正是这些过程决定着光纤乃至整个光缆的可靠性和稳定性。让我们概略地看一下对有关光纤老化与损坏问题的主要研究方面的工作情况。众所周知,光纤的物理机械特性在受到下列外部环境作用时均会发生变化:机械、温度、表面活性介质、放射性辐射等。光纤损坏现象业经过详细实验研究,已普遍共知,但其理论阐述至今却远未完善。这是因为损坏过程看来筒单,其机理确实极 Optical fiber by the external impact of aging and damage process research results, has caused a great interest in cable communications experts. It is these processes that determine the reliability and stability of the fiber as well as the entire cable. Let’s take a brief look at the main research work on fiber aging and damage. As we all know, the physical and mechanical properties of optical fiber are subject to the following changes in the external environment: mechanical, temperature, surface active media, radioactive radiation. Optical fiber damage phenomenon after a detailed experimental study, has been generally known, but its theory is far from perfect. This is because the damage process seems to be one-sided, and the mechanism is indeed extremely positive
