Abstract

The impact of exposing an optical fiber to 6 MeV electrons on the performances of Optical Frequency Domain Reflectometry (OFDR) distributed sensors is investigated. Six different types of optical fibers with different core compositions and coatings have been tested: four fibers are metal-coated (copper, gold or aluminum) for high temperature (> 300°C) operations while the two others have Telecom-grade acrylate coatings for operation below 80°C. The fiber Rayleigh signature used to perform the OFDR sensing remains almost unaffected after an electron exposure. Indeed, the measured radiation-induced temperature errors are lower than about 3°C, close to the setup uncertainties, when the OFDR operates as a temperature sensor.
