    Abstract: In a known optical component a cylindrical glass core of synthetic quartz glass contains hydroxyl groups, a maximum 200 wt.-ppm of chlorine, and no dopant in the form of a metal oxide. The glass core is axially enveloped by a glass mantle of doped quartz glass which has a lower refractive index than the glass core. Setting out from this, in order to offer an optical component of quartz glass for broad-band transmission, especially for broad-band spectroscopy, which is characterized by low attenuation over a broad range of wavelengths, it is proposed by the invention that the core glass contain less than 5 wt.-ppm of hydroxyl groups.

    Abstract: A large optical preform 303 is made by a modified chemical vapor deposition (MCVD) process by depositing successive layers of core and cladding materials onto the inside surface of a rotating glass tube 33 having a hydroxyl ion (OH.sup.-) level that is less than 0.5 parts per million (ppm) by weight. The tube is then collapsed inwardly to form a core rod 301 in which the deposited core material 31 has a diameter that is greater than about 5 millimeters and the deposited cladding material 32 has an outside diameter that is less than about 15 millimeters. A machine-vision system 140, 150, 160 monitors and controls the diameter of the glass tube by regulating the pressure within the tube. Moreover, the machine-vision system monitors and controls the straightness of the tube by varying its rotational speed according to angular position. After the core rod 301 is formed, it is plasma etched to remove contaminants, and then overclad with two glass jackets 34, 35 having a hydroxyl ion (OH.sup.-) level that is less than 1.0 ppm by weight to create a large preform 303 from which about 400 kilometers of singlemode optical fiber can be drawn per meter of length.
