Optical Wireless Hybrid VLC/OCC System Based on a Single Centralized LED

Abstract

In this paper, we present the experimental demonstration of a hybrid visible light communications (VLC) and optical camera communications (OCC) system based on a single centralized light emitting diode (LED) coupled with a plastic optical fiber (POF). Two data streams of SS Mb/s and 4 kb/s are point-to-point transmitted simultaneously and passively distributed over a 20 m POF and 3 m free space optics links (FSO), where high- and low-speed signals detection is provided by a photodiode (PD) and an optical camera-based receivers, respectively. The system aims to provide different services and/or applications to the end-user regardless of the employed devices with the lack of intermediate electro-optic conversions, network simplicity and low cost, as major advantages.
