Abstract
The technologies of spectral multiplexing of communication channels and spatial multiplexing in fiber-optic communication lines are considered. The flow of scientific and technical literature in the field of research of technologies of spectral channel multiplexing and technologies of spatial multiplexing is analyzed. Based on the previously proposed methods for analyzing publication activity, an assessment of the technological involvement of various countries was carried out, and the stages of development of technologies for spectral and spatial multiplexing of communication channels were identified. Data on the dynamics of publications in the time interval of 2017-2022 are presented, which make it possible to predict the involvement of various teams in research on these topics. The groups of countries where the most competent research groups in the field of spectral division multiplexing and spatial multiplexing are working are determined. A list of organizations that most actively fund research on the considered technologies has been identified. The distribution of publication activity in the following fields of knowledge is presented: spectral multiplexing of communication channels and spatial multiplexing of communication channels. Based on a comparative analysis of the dynamics of the publication activity of the two directions, the main trends in the development of promising developments in the technology of spectral division multiplexing and spatial multiplexing are determined.
