In connection of importance of application vitreous Si02 (v-Si02) in the nuclear industry do not weaken attempts to receive this material with high stability to influence of radiation. The description of a method of reception of the preliminary form of glass possessing optical stability to action of radiation for manufacturing a glass fiber waveguides is submitted in work.
On the basis of glass fiber waveguides various types of the gauges - acoustic, magnetic, temperature, gauges of pressure and etc., are developed. Optical fiber waveguides are used for transfer of a signal both on short and on a long distance. Transfer of a signal on short distances is carried out with use of fiber waveguides with losses much exceeding losses in waveguides on a long distance. If to accept reguirement showed to optical material for optical fibre communication lines that loss of light on working length of a wave should be less than 10 db/km for long lines and less than 50 db/km for short lines which length makes 100-300 m [1]. However, if fiber glass is maintained in conditions of radiating influence that it results in essential change of its optical characteristics and causes the raised losses of an information signal. So for example fiber glass with a core from V-Sİ02 and an environment from V-SiO2 + V-B2O3 at λ=0,82µm, value absorption coefficient α ~ 11 db/km and at a dose of an irradiation ~10(3) rad α~1000 db/km [2]. From these data follows that in a zone of an irradiation it is possible to maintain only fiber glasses subjected by rather low doses of radiations.
