Optical fibers have been used in the petroleum industry for many years; their applications range from real-time temperature and pressure measurements, data transmission, to imaging applications. In this paper, we demonstrate significantly improved reliability of recently developed hermetic, high operating temperature optical fiber. The study includes extensive testing of this fiber under controlled conditions; and a comparison with previous studies and other non-hermetic fibers.
