2022: Optical Fiber Durability Technology Presentation
March 23, 2022 Perm Politech said that his scientists have developed technology that will increase durability optical fiber when working in extreme operating conditions. Optical communication is one of the main methods of transmission. data In addition to -, Internetproviders quartz fibers are already used for, lasers gyroscopes, data transmission to and. oil wells In space this regard, the requirements to optical fiber for strength, corrosion resistance, operating temperature and other properties are constantly increasing.
The results of the study were published in the journal Izvestia of Universities. Powder metallurgy and functional coatings 2021. "
Scientists around the world are studying the issue of fiber strength, but the study of its crack resistance, according to the university, has no analogues. The method of developers of Perm Polytechnic University is associated with an increase in the durability and operability of fiber in various media (influence of high and low temperature, diffusion of hydrogen or ionizing radiation).
It was possible to increase crack resistance and extend the service life due to a change in the drawing technology.
"The process of drawing fiber began on the top of the tower, where the blank was fixed in a centering cartridge. The end of the preform was placed in a high temperature furnace, where it was heated to 2100 ° C and slowly dropped to the outlet of the furnace. At this time, polyimide varnish was applied to it. Thus, it turned out that the polyimide coating has a positive effect on the strength and stability of the fiber, "- shared graduate student of the department "Metal Science, Thermal and Laser Processing of Metals" Maxim Bulatov. |
"The technology will be used in places where aggressive parameters need to be monitored on an ongoing basis. For example, in oil wells, submarines, nuclear power plants, etc. Therefore, crack resistance testing is important, as it is the main parameter of material viscosity and in many cases plays a major role in predicting life, " said Doctor of Technical Sciences, Professor of the Department of Metal Science, Thermal and Laser Processing of Metals Alexander Shatsov. |
As of March 2022, a large number of statistical tests are being carried out.
It is known that they became interested in the development of polytechnics in Perm Scientific and Production Instrument-Making Company scientific the center, fiber optics RAS Permgeokabel and at the plant "."Incab
The technology of scientists at PNIPU won the Russian Scientific Foundation together with the A. M. Prokhorov Institute of General Physics of the Russian Academy of Sciences 22-29-00795 "Predicting the operability and degradation of fiber fibers in extreme operating conditions."
