An optical waveguide fiber with a titanium dioxide - silicon oxide - outer jacket and a method for the production thereof.

摘要

An optical waveguide fiber with a fatigue resistant TiO.sub.2 - SiO.sub. 2 outer cladding including a cylindrical outermost layer with TiO.sub.2 concentration greater than 10.5 wt. % and thickness less than 3 &mgr;m. The fiber may include a two layer outer cladding with higher TiO. sub.2 concentration in the outer layer. The outer cladding may include a plurality of inhomogeneities dispersed in a TiO.sub.2 -SiO.sub.2 matrix.
