Paper Abstract

Among numerous glass forming systems, only a few of them give glasses stable enough to be drawn into fibers. Fluoro-zirconate glasses which have been extensively studied provide industrial infra-red transmitting fibers with optical losses well lower than 1 dB/m between 1 and 4 μm, and transmission losses lower than 5 dB/km have been observed on experimental fibers. Experiments carried out on fluoroaluminate and fluorozincate glasses result in fibers of several dB/m in optical attenuation. Wavelength independent scattering which is the main source of losses arises from bulk crystallization while surface defects dramatically reduce fiber strength. Control of surface devitrification and optimization of glass composition are the major elements of further development.
