The paper considers a simplified method for calculating the geometric parameters of an optical fiber with many cores. Such a fiber allows for an increase in the throughput of fiber-optic transmission systems by the method of spatial multiplexing. The proposed technique is based on the concept of light energy distribution in the mode spot and the allowable level of mutual influence between different cores. Algorithmic and software that implements the proposed technique has been developed. A comparative analysis of the triangulation and rectangular structure of fiber with many cores was performed. The technique considers the influence options from the nearest cores and the far layers cores. The analysis of the stability of the received results to minor deviations of actual parameters from the accepted ones in the model is executed. The technique is resistant to minor deviations in the shape of the cores from the circular and to small bends of the optical fiber. The method’s theoretical basis is used representations of wave optics and relatively simple representations of geometric optics. The obtained formulas are quite simple to analyze. Therefore, the obtained results can be offered for fast analysis of complex geometric structures of an optical fiber with many cores. Direct measurements or more complex theories compared the obtained results with the known estimates. It is shown that more than 100 cores can be concentrated in a fiber with a diameter of 200-400 μm, taking into account the typical values of noise in real fiber-optic transmission systems. That is, with a slight increase in the size of the optical cable, you can increase the total transmission rate by more than 100 times.

“…В даному випадку слово «резонанси» взято у лапки тому, що коефіцієнти у формулі (5) визначаються за результатами вимірювань методом підгонки [2,4], а тому обчислені довжини хвиль k l не обов'язково співпадають з будьякими довжинами хвиль атомних або іонних резонансів. Відмітимо, що модель у формі (5) широко використовується у сучасних наукових дослідженнях [17][18][19][20].…”

The paper considers a group of polynomial models of various characteristics of an optical fiber (OF) depending on the wavelength and chemical composition of the fiber. A method for structural identification of such models is proposed. The following characteristics are considered: the refractive index of the fiber core and cladding, group refractive index, group velocity, dispersion coefficients, numerical aperture, cutoff wavelength of the fundamental mode, etc. An analysis of the well-known Cauchy, Lorentz-Lorenz equations, Sellmeier’s formulas, etc. is given in relation to the problem being solved. The applied method of structural identification provides for the decomposition of a complex computational problem into simpler ones. This technique involves the identification of polynomial models for different samples of a substance. After that, structural identification is performed by the parameter of the additives to quartz glass. The proposed method and models are tested on the example of parameter values: the wavelength range is from 0.8 to 1.8 μm, the type of optical fiber is single-mode, and the refractive index is stepped. For calculations, the tabular values of the coefficients of the Sellmeier formula for SiO2 with GeO2 additions from 0% to 13.5% were used. It is shown that the dependence of the main characteristics of OF on wavelength and chemical composition is modeled with sufficient accuracy by a polynomial model. Indicators of the highest degree on two arguments can be limited to the third degree. The synthesized models have an interpolation and extrapolation error in the considered ranges of the order of 0.001%. This makes it possible to recommend them for scientific and engineering applications, as well as for solving problems of the production of organic matter with predictable characteristics.
