Fiber optic cable twisting and deformation
When an optical cable is bent or twisted, the fibers inside the cable can be damaged. This damage can take several forms, including micro-bending, macro-bending, and stress-induced attenuation. Micro-bending occurs when the fiber is bent at a small radius, typically less than. This study investigates the strain transfer mechanism for different types of fiber optic cables while embedded in concrete cubes, sustaining a boundary condition which features a displacement discontinuity. Fiber optic cables are widely used for high-speed data transmission in optical engineering applications.
