<title>Measurements and results of gamma-radiation-induced attenuation at 980-nm of single-mode fiber</title>

Abstract

Radiation testing of 980 nm single mode optical fiber, at 120 krads total dose was performed at three temperatures (minus 30 degrees Celsius, plus 96 degrees Celsius, and room temperature). Testing was also performed on samples from different sections of the optical fiber drawn from a single preform that was designed for a lower cutoff wavelength this fiber is referred to as (Flight), and an off-the-shelf (OTS) 980 nm optical fiber from the same manufacture. The results of this data are discussed in this paper and a projection of the damage to the optical fibers over a five year period was done using the n<SUP>th</SUP> order kinetic model developed by J. Friebele et al.
