Kinetic model for radiation-induced attenuation in silica-based optical fibers: analysis of generation and annihilation of two leading color center defects

In this study, a radiation-induced attenuation (RIA) kinetic model based on color center density is developed by considering the effects of dose, dose rate, and temperature on RIA in optical fibers. Due to the different experimental conditions of fiber irradiation decay-related studies, there are differences in RIA kinetic models based on different fiber types, dopants, and irradiation dose ranges. Based on the paper of typical comparison scope, this paper constructs an RIA model with certain generality. The proposed RIA kinetic model successfully fits the correspondence between RIA and dose, dose rate, and temperature parameters in different optical fibers. The research results will provide a theoretical basis and data reference for the application selection and whole life cycle assessment of fiber-optic communication systems in the field of the particular radiation environment.
