Analytic Models for Radiation Induced Loss in Optical Fibers III. Transient Radiation Effects.

Abstract : A number of physical models used to describe the recovery of transient radiation induced loss in optical fibers were evaluated and found unacceptable for various reasons. Based on an approximation to some of these models, the analytic expression L = a/(1 + b(t to the nth power)) where L = loss, time = time after pulse, and a, b, and n are constants, was formulated and found to give very good fits to transient radiation effects data obtained at RADC.
