    Abstract: Method wherein continuous indexed lengths of optical fiber are automatically measured for load at failure for each failure below a predetermined maximum stress. A predetermined length of optical fiber is indexed. The optical fiber is clamped at one or more clamp points along its length. Increasing tension is applied to a first indexed length of optical fiber between at least one clamp point and a tension application means. Increasing tension is applied between an initial value and the predetermined maximum load. The increasing tension is measured during its application. If failure occurs, the actual load at failure is detected while the increasing tension is being applied. When failure does not occur, the first length of optical fiber is released and a second length of optical fiber is indexed to the position where increasing tension is applied to the second length between at least one clamp point and the tension application means.

    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.

    Abstract: A method of making a strengthened glass article includes providing a flat glass article having a select contour and a glass surface covered by a protective coating layer. The protective coating layer is removed from the glass surface without touching the glass surface with any solid object. Immediately after the protective coating layer is removed from the glass surface, the flat glass article is subjected to an ion-exchange process to strengthen the flat glass article and improve the resistance of the flat glass article to subsequent damage.
