New Type of VLC Communication Transmitter Based on Optical Fibres

This article presents new insights in the research of VLC communication transmitter based on multimode optical fibres. Optical transmitters are formed by a different number of optical fibres. These fibres illuminate the defined surface area in the form of the 1/8 of the sphere, which simulates the room corner. The aim of this article is to point to possible new trends in the field of research such a transmitter and its construction. The simulation issue of given type of transmitter in LightTools software will be introduced (the optical fibre deflection angle adjustment, forming the fibre ends) and then the comparison of simulated and real data will be verified. Optical power parameters are monitored in individual cuts of the 1/8 of the sphere are monitored. Here, the requirement is the decrease of the maximum value against to the minimum value not exceeding 3 dB.
