The operating temperature of common acrylic-coated optical fibers is usually -65 °C to 80° C, and the working temperature of common high-temperature polyimide-coated optical fibers is up to 300 °C. At higher temperatures, metal-coated special optical fibers, such as aluminum-coated, copper-coated, and gold-coated fibers, are usually used for signal transmission. In this paper, the transmission loss of gold-coated fibers is tested at different ambient temperatures, and it is found that the transmission loss of gold-coated fibers varies greatly when the ambient temperature changes. For fiber optic temperature sensors based on the blackbody radiation principle, the error introduced by the variation in transmission loss can exceed 60 °C. On this basis, based on the transmission characteristics of light in different bands in gold-coated fibers, a dual-band correction method is proposed, which can correct the transmission loss of optical fibers caused by ambient temperature. After the correction, the error caused by the transmission loss is less than 15 °C.
