The induced attenuation and subsequent recovery were measured at 20xC and -50xC employing two different light power levels at each temperature. Results will be presented and compared for the various conditions and OH/Cl content differences. Implications for mechanisms of defect growth and recovery will be presented.enCl contentcontinuous irradiationlow temperatureOH contentoptical fibrespulsed irradiationradiation induced lossroom temperature620conference paper
