Abstract: In a known method, a quartz glass component is produced for a UV radiation source by melting SiO2-containing grain. Starting therefrom, to indicate an inexpensive method by means of which a quartz glass component is obtained that is characterized by high radiation resistance, it is suggested according to the invention that synthetically produced quartz crystals are molten to obtain a pre-product which consists of quartz glass containing hydroxyl groups in a number greater than the number of SiH groups, and that for the elimination of SiH groups the pre-product is subjected to an annealing treatment at a temperature of at least 850° C., whereby the quartz glass component is obtained. In the quartz glass component of the invention, the quartz glass is molten from synthetically produced quartz crystals, and it has a content of SiH groups of less than 5×1017 molecules/cm3.

Abstract: An optical fiber preform is assembled by inserting core rod segments axially end to end inside of a first glass overclad tube having a first, relatively low concentration of a given impurity that contributes to signal attenuation in an optical fiber to be drawn from the preform. The first overclad tube with the contained core rod segments are inserted in a second glass tube having a second concentration of the given impurity which is higher than the first concentration. The wall thickness of the first overclad tube is preferably less than that of the second overclad tube, thus reducing the amount of high purity glass needed to form the first overclad tube and attendant manufacturing costs. The core rod segments may include salvageable remnants from a single long core rod produced, for example, by vapor axial deposition (VAD).

Abstract: Known synthetic quartz glass tubes for the production of a preform have an inner bore with a surface layer produced without using tools in the molten state and an inner zone. The aim of the invention is to provide a tube which does not release any OH groups to the surroundings. For this purpose, the surface layer (30) has a thickness of 10 μm and an average OH content of not more than 5 ppm by weight and an average surface roughness Ra of not more than 0.1 μm. The inner zone (34) that starts on the surface layer (30) and terminates 10 μm before the outer wall has an average OH content of not more than 0.2 ppm by weight. A simple and inexpensive method for producing a quartz tube of the above type is to continuously draw a tube strand from a softened quartz glass mass in a vertical drawing process. A scavenging gas is circulated through the inner bore of the tube, said gas having a water content of less than 100 ppb per weight. The front end of the tube strand (19) is closed by a flow obstacle (26) that is permeable the scavenging gas and that reduces the amount of scavenging gas (23) flowing through.

Abstract: Jacket tubes of synthetically produced quartz glass as a semi-finished product for producing an outer cladding glass layer of an optical fiber are generally known. The invention relates to an improvement of a jacket tube in terms of inexpensive producibility and of suitability as a semi-finished product for optical fibers having a low optical attenuation. According to the invention this object is achieved by a jacket tube in which the quartz glass has a content of metastable OH groups of less than 0.05 wt ppm and a content of anneal-stable OH groups of less than 0.05 wt ppm.
