INSTRUMENT FOR MEASURING THE ULTIMATE STRENGTH OF OPTICAL FIBERS
The main problem that the practice solves is to overcome one of the main reasons for the unsatisfactory installation of fibre optic connections in the BRICS and CIS countries - the use of low-quality optical fibres by companies during installation and the blaming of all problems on the installers, which creates a vicious circle. This problem is particularly acute in the Russian Federation and the Republic of Armenia, because in the first case the work of many government agencies that are vital to the country, such as the Russian Ministry of Health, is hampered or made impossible, while in the second case there are communication problems within the agencies due to a fundamentally different approach to remote reception of citizens. For example, serious problems arise in the interaction between the State Revenue Committee of the Republic of Armenia and the State Committee for Real Estate Cadastre, which can lead to litigation for law-abiding citizens. Practice offers the following solution to the problem: express diagnostics of a certain part of a batch of optical fibres with a portable device, which allows to make a conclusion on the whole received batch for a small number of measurements, which will allow to determine without errors the mechanical reliability at a certain technique of installation - researches in this field have been conducted since the end of the 70s with the support of such structures as Bell Labs, even after leaving the AT&T company, and the U.S. Navy, which ensures the reliability of the results obtained in the course of their application. In the end, this will make it possible to significantly reduce the rate of line failures, both by directly improving the quality of the work carried out by the company's employees and, if necessary, by choosing a different strategy for laying fibre optic cables. The practice has an important additional feature: it is not tied to a specific type of optical fibre, thanks to the availability of a set of working profiles in the on-board computer of the device, which are responsible for different types of optical fibres. These profiles can be adjusted over a wide range of limits in a way that is accessible to the experienced PC user, so that there are no problems with their practical application, provided that they are physically correct. This fact is guaranteed by the deep level of immersion of the practitioners in the subject of two-point bending of various multilayer rods (in general, strength tests can be carried out on any multilayer rod with a sufficiently low theoretical resistance to bending, obtained by means of deductions from the theory of elasticity, for example, from the inference of rod bending, or, for special accuracy of the model, from the bending of a cylindrical shell or cylinder).
