In this study, a large-core optical fiber is fabricated by modified chemical vapor deposition (MCVD) was employed and the effects of temperature on its optical properties were investigated. At a temperature range of −100℃~100℃, it was found that the transmission loss coefficient of the first window (850 nm band) was changed at a range of 2.487dB/km∽ 4.27dB/km, and at the range of 0.96dB/km∽ 7.575dB/km for the second window (1050 nm band). Further the transmission loss is increased at the end of both high and low-temperature sides and a large fluctuation was notices. Electron paramagnetic resonance indicated that there are no paramagnetic defects in the fiber. Additionally, it was also found that the optical transmission loss coefficient decreases gradually from 3.095dB/Km to 2.353dB/Km after 30 days then becomes stable..
