In this work we characterize the mechanical properties, like the elastic constant, the Young modulus and the mean strain limit for commercial optical fibers. Nowadays, optical communications are the most requested and preferred telecommunication technology, due to its large bandwidth and low propagation attenuation, when compared with the electric transmission lines. The results of this study will assist researchers and engineers to select appropriate cables for strain sensing and interpret the fiber optic sensing. It covers cables for repeatered, repeaterless, and dedicated sensing systems, designed for deep and shallow waters. Submarine cables are categorized by protection levels:. Optical fiber strain sensing cables are widely used in structural health monitoring; however, the impact of a harsh environment on them is not assessed despite the huge importance of the stable performances of the monitoring systems. This paper analyzes (i) the impact of the different constituent. The document details the design, mechanical properties, and performance characteristics of optical fiber cables, highlighting aspects such as fiber flaws, microbending, and the effects of hydrogen absorption and nuclear radiation. The strain transfer mechanisms for different cables are compared under increasing strain.
