Exposure of optical fibers to high radiation dose rates can cause a transient increase in the optical attenuation of the fiber as well as induce significant luminescence. High levels of transient attenuation can interrupt the operation of optical data links. Transient radiation induced upset of the transmitter and/or receiver can interrupt the operation of an optical fiber data link by combining the assessments of the three separate parts. The recovery characteristics of the optical fiber, transmitter, and receiver can be used to predict the recovery of a data link.
