Optical fibers for communication transmission having high stability to nuclear radiation

摘要

An optical fiber comprising a light-conducting core and a borosilicate glass optical insulation cladding thereon is stabilized against the effects of nuclear radiation by incorporating in the core and the cladding an amount of Sb2O3 effective to harden the fiber against nuclear radiation. Amounts of 0.002-6 wt. % Sb2O3 are generally useful.
