description: This paper considers methods for controlling the mode composition of microstructured fiber at all production cycles to obtain low-mode fiber, a method for detecting optical vortices, a method for measuring the level of an optical signal and attenuation in optical fibers. The scheme for controlling the mod composition is presented. The features of the developed method for controlling the mode composition and the method for creating and drawing microstructured fibers are described. A method for creating a microstructured fiber preform by assembling a geometric structure from capillaries is presented. To create twisted fibers, a modification of the suction tube feed unit was created. The results of theoretical calculations of the geometric parameters of the structure and the propagation of the mode composition inside the microstructured fiber in the COMSOL program are presented. An interference scheme is assembled for detecting optical vortices inside a microstructured fiber. The results of drawing microstructured fibers of various types of geometric parameters are presented. The results of a study of the mode composition and the presence of optical vortices inside an elongated fiber are presented.
