Abstract: An optical waveguide fiber with a core region 1 and a cladding region 2, wherein said cladding region 2 includes an outer cladding region 3 is disclosed wherein said outer cladding region 3 is a very thin (less than 1 mu m in thickness) layer of Ti02-Si02 glass which results in a substantial reduction in the number of fiber breaks resulting from the fiber drawing process and having a predetermined Ti02 concentration less than or equal to about 10 wt. %. A method for making said fiber is also discussed.

Abstract: Disclosed is a dispersion shifted single mode optical waveguide fiber having a segmented core refractive index profile in which the profile parameters are selected to provide an attenuation minimum. A set of profiles having the same general shape and dimensions is shown to have a group of profiles contained in a sub-set which exhibit a minimum of attenuation as compared to the remaining members of the set. The members of the sub-set have been found to have the lowest effective group index, ngeff, and the lowest change in beta under waveguide fiber bending.

Abstract: An optical waveguide fiber with a fatigue resistant TiO2-SiO2 outer cladding including a cylindrical outermost layer with TiO2 concentration greater than 10.5 wt.% and thickness less than 3 .mu.m. The fiber may include a two layer outer cladding with higher TiO2 concentration in the outer layer. The outer cladding may ionclude a plurality of inhomogeneities dispersed in a TiO2-SiO2 matrix. A method of making an optical waveguide fiber with a fatigue resistant TiO2-SiO2 outer cladding, and a substantially glass blank for drawing into such fiber, wherein a glass soot TiO2-SiO2 outermost layer, with an initial TiO2 concentration greater than 10.5 wt.%, is deposited on a preform, and the preform is exposed to an atmosphere of chlorine at a high temperature, and the resulting TiO2 concentration in the outermost layer of the TiO2-SiO2 outer cladding of the substantially glass blank is less than the initial TiO2 concentration. In the glass blank form, the outermost layer includes a substantial volume percentage of crystalline phases and in the fiber form, the outermost layer includes inhomogeneities.
