Using MCVD-technology, radiation-resistant multimode optical fibers based on fluorosilicate glass with a gradient refractive index profile were developed. Radiation-induced attenuation of light (RIA) in the fibers was compared with the literature data on analoguous fibers manufactured by the PCVD-technoogy. It was found out that RIA in the MCVD-fibers at the wavelength λ=1310 nm under γ-irradiation at doses of up to 10 kGy is 1-2 dB/km (19%-29%) lower than RIA in Super RadHard fiber produced by the PCVD-technology and previously supposed to have record-high radiation resistance.
Разработана технология изготовления, освоено серийное производство и проведены испытания оптического волокна с кварцевой сердцевиной стойкого к повышенным температурам, ионизирующему излучению и водородосодержащей среде. Такие оптические волокна могут быть использованы в кабелях для специальных систем телеметрии, бортовых кабелях авиакосмической техники, геофизических кабелях для измерения температуры в скважине.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
