Analysis of the Useful Life and Health Management for Optical Fiber Links in Data Centers

Optical cables serve as the foundation of communication network, carrying the vast majority of data flow, especially bulk data services in data centers. When optical fiber links fail, it would severely impact information communication. This paper analyzes the failure mechanisms of optical fiber links, summarizes the main factors influencing the useful life of optical fiber links, and establishes a multi-stress degradation model to further clarify the relationship between them. Building on that, reasonable suggestions for health management of optical fiber links are proposed, aiming to enhance the reliability and stability of information transmission and extend their useful life.
