Today, it is not possible to abandon modern sources of information; with such rapid development of technology, we need to analyze large amounts of data. To a greater extent, applications that require speed and volume of transported information are responsible for the increase in transmitted data, such as streaming and cloud data processing services, as well as traffic transfer between data centers. The experimental part of the research involves several schemes for distributing a quantum channel inside a multi-core fiber, as well as different models for placing classical channels. To transmit the quantum channel, scientific and educational complexes developed by the Qrate company were used; the transmission of the quantum channel was implemented based on the BB84 protocol. The article analyzes experimental studies on the parallel transmission of three quantum channels in a multi-core optical fiber with satisfaction of the quantum bit error rate and key length, as well as a study of the influence of classical power on the transmission of a quantum channel along the adjacent core of the fiber under study. Such research provides a new direction for the development of microstructured fibers specifically for the needs of quantum communications.
