Abstract

Attempts have been made to use optical fibers as signal transmission lines in radiation fields as in nuclear reactor facilities etc. For use in such high-radiation fields, it is not infrequently required that the fiber be resistant not only to radiation but also to heat. We have already demonstrated that the pure-silica core optical fiber fabricated by the MRT process¹ has high-radiation resistance.² Based on our research conducted on jacket materials, we propose a new radiation- and heat-resistant fiber for actual use.
