Abstract
A process whereby an optical fiber is hermetically coated with a layer of aluminum oxide. The fiber is reacted pyrolytically with organo aluminum derivatives or other aluminum compounds, either in the form of vapor or atomized spray, to produce the desired coating. The thickness can be varied by changing reaction parameters. A buffer is also applied to the coated fiber. The end product is a glass fiber impervious to gases and fluids in the environment, especially H.sub.2 O, and one of improved abrasion resistance, hardness and strength.
