Radiation Resistance of Glass Fiber Optic Cable

Popis výsledku v původním jazyce

The good experience with optical communication and its advantages in industrial applications have lead to introduction of optical communication technology into more conservative areas, such as the nuclear and aerospace industries. The number of optical cables in nuclear power plants has been increasing. Fiber optic cables are commonly used at nuclear power plants in I&C systems but they are usually used in mild environments, i.e. without radiation. Nevertheless, currently, the number of applications in harsh environments with radiation is increasing. One of the most prevalent effects of radiation exposure is an increase of signal attenuation (signal loss). This is the result of fiber darkening due to radiation exposure and it plays a very important role in application of fiber optics in radiation environment. However, after the irradiation, the fiber optics go through a “recovery process” during which the optical properties improve again. As we discovered, this healing process can stop and switch its trend.
