In this paper we consider the question of creating a secure data environment in an organization based on technology VLC (Visible light communication) with the use of PLC (Power line communication) modem. The study analyzes the domestic and foreign literature and patent documents, which confirmed the relevance of the subject and the need to improve and adapt technologies to local organizations, grounded potentially better protection against unauthorized access to data in comparison with wired and Wi-Fi networks The structural scheme of realizing data transmission based VLC technology involving the use of LED light sources as a transmitter of a communication system with the integration of PLC interface. Using the PLC interface simplifies installation and implementation of the VLC transmitter modules, since the data signal is supplied to the latter on power lines providing power lighting. An assessment of conditions based on the technology transfer system functioning VLC with PLC interface, found that at the lowest acceptable signal / noise ratio equal to 6 dB bandwidth of the channel is equal to 8Mbit / s, and the bit error rate tends to zero. The research results can be used by VLC technology building enterprise network to the PLC interface, also find application for further study of this technology.
