ABSTRACT:
An infrared optical fiber is provided which includes silver halide polycrystals having a composition ratio of silver chloride and silver bromide in the range of 30 to 70 percent by weight of silver chloride, and having an average grain size of 5 .mu.m or less. There also is provided a method of manufacturing such an infrared optical fiber, in which a silver halide single crystal having a composition ratio of silver chloride and silver bromide in the range of 30 to 70 percent by weight of silver chloride is extruded into an infrared optical fiber, while applying an extruding pressure of 70 kg/mm.sup.2 or more and a tensile load which is greater than the yield strength and smaller than the tensile strength.
