These are typically caused by mechanical pressure from surrounding materials, temperature-induced contraction, or uneven surfaces in cable design. In this paper, the microbending optical losses induced by the packaging of a sensing optical fiber into a sandwiched glass-fiber reinforced structure are investigated experimentally and by simulations. In fiber optics, "bending" refers to the way in which light travels through a fiber optic cable. The paper highlights key factors influencing bending sensitivity, enhancing reader. Bending losses are influenced by different optical parameters like Mode Field Diameter (MFD), Cut-off wavelength and MAC value.
