    Abstract: A process for producing synthetic quartz glass using a burner composed of a plurality of concentric nozzles involves the steps of feeding a silica-forming raw material gas and a fluorine compound gas to a reaction zone from a center nozzle, feeding oxygen gas from a second nozzle outside the center nozzle, and feeding oxygen gas and/or hydrogen gas from a third nozzle. The silica-forming raw material gas is hydrolyzed to form fine particles of silica, which particles are deposited on a rotatable substrate so as to form a porous silica matrix, which is then fused to give the quartz glass. The flow rate of the oxygen gas fed from the second nozzle and the flow rate of the raw material gas are controlled so as to provide a 1.1- to 3.5-fold stoichiometric excess of oxygen. The excess oxygen suppresses Si—Si bond formation in the quartz glass, enabling the production of synthetic quartz glass having a high transmittance in the vacuum ultraviolet region.

    Abstract: In a known procedure for the manufacture of an optical fiber by drawing from a preform with a core-clad structure or from a coaxial arrangement of several components forming a core-clad structure, a core cylinder is produced with a soot deposition method, with the core cylinder having a core glass layer of a higher refractive index, nullnKnull, and outer diameter, nulldKnull, said core glass layer being encased by a first cladding glass layer having a lower refractive index, nullnM1null, and outer diameter, nulldM1null, followed by applying a second cladding glass layer onto the core cylinder. The modification of this procedure according to the invention is characterized by its lower optical fiber production costs. This is achieved by providing the second cladding glass layer (4) in the form of a cladding tube manufactured in a separate step of the procedure, said cladding tube having a mean OH concentration of max. 1 wt.-ppm, and applying the second cladding glass layer (4) by collapsing the cladding tube onto the core cylinder (2; 3), and by using a core cylinder with a nulldM1null/nulldKnull ratio between 1 and 2.2 and a mean OH concentration of max. 1 wt-ppm in its superficial area up to a depth of 10 nullm (FIG. 1).

    Abstract: An optical fiber is formed by performing vapor phase deposition of SiO2 on the outside of a glass rod comprising a core section and a first cladding section and drawing a glass preform which formed by a second cladding section. Also, a single mode optical fiber is manufactured so that the ratio of the diameter D of the first cladding section and the diameter d of the core section is in a range of 4.0 to 4.8, and OH concentration is 0.1 ppm or less. Also, an optical fiber is manufactured so that a value of D/d>4.8, and the OH concentration is 0.1 ppm or less. It is thereby possible to maintain an initial loss in the 1380 nm wavelength range even if hydrogen diffusion occurs.
