This paper reports recent achievements in the field of infrared optical fibers based on vitreous arsenic chalcogenides (As2S3, As2Se3, As2Se1.5Te1.5). The minimum optical losses of the fibers from arsenic sulfide, arsenic selenide and arsenic telluride are equal to 20 - 30 dB/km at 2.2 and 3.3 micrometers , 80 - 100 dB/km at 4.3 micrometers , and 100 - 300 dB/km and 6.7 micrometers , respectively. Among them the double polymer coated two-layer arsenic-sulfide optical fibers have the lowest optical losses (20 - 25 dB/km) and the highest mechanical bending strength (1 - 1.5 GPa).
