Caused by optical 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 a. Optical fibers are made of glass or plastic, and are designed to transmit light signals through their core. 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. In the exploratory Fiber Optic (FO) cables used in the Atlanta Fiberguide System Experiment, 12 optical fiber ribbons each containing 12 fibers are stacked one on top of the other to form a rectangular array of 144 optical fibers.
