description: The given work is devoted to development of a methodology for theoretical and experimental analysis of intermode interference signals to evaluate and determine the mode composition of a multimode fiber fiber.. Terminological features of the subject area are considered and the software tools for solving the problems are applied. Specialized software and mathematical software Mathcad and Wolfram Mathematica are used. The present work is a theoretical and practical research, including analysis of relationships between the parameters of multi-mode fibre optical fibre and spectral characteristics, comparison of model calculations and experimental measurements. The first section is devoted to the analysis of existing methods for investigating the characteristics of a multi-mode fibre light guide using intermode interference. The second section is devoted to theoretical modelling of intermode interference signals in a multi-mode fibre lightguide. The third section is devoted to the experimental study of the spectral characteristics of intermode interference signals and their relationship with the parameters of the multimode fibre lightguide.
