    Abstract: A method of protecting a silica-containing article (10) used in the manufacture of an optical fiber includes the step of applying to the silica- containing article a protective layer (30) that facilitates removal of particulates (20) that deposit on the protective layer (30) and that ablates during or can be removed before subsequent processing of the silica-containi ng article (10). An intermediate product used in the manufacture of an optical fiber and protected against break-inducing particulates (20) includes a sili ca- containing article (10), and a protective layer (30) that facilitates remova l of particulates (20) that have deposited on the protective layer (30) and th at can be ablated during or removed before subsequent processing of the intermediate product.

    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: Disclosed is a method of proof testing a sheet of brittle material such as a glass or glass-ceramic based material. The method comprises bending the glass sheet over at least one arcuate member to detect sheets having a strength greater than a predetermined value. The method includes imparting a bend to the sheet and producing relative motion between the sheet and the bend such that the bend traverses the sheet, and wherein tensile stress induced in a surface of the sheet by the bend corresponds to the predetermined strength value. An apparatus for performing the proof testing is also disclosed.
