Defining effective bending radius and stress-optic coefficient values using bend loss measurements

This study explores a method for determining the effective bending radius (Reff) and stress-optic coefficient (C2) values in optical fibers through bend loss measurements and simulations. By analyzing the relationship between bending-induced losses, dopant material content, fiber geometry, and refractive index profile, we gain a better understanding of the factors influencing fiber performance in practical applications.
