Abstract

Visible light communication (VLC) is a wireless technology that uses visible light as a carrier to transmit the signal. Visible white light is the combination of three basic colors that are red, green and blue. These different colors are generated by using different color LEDs which are operated at different wavelengths according to their respective colors. These LEDs are operated by different data signals, and then by using the wavelength division multiplexing (WDM), these optical modulated data signals are converted into a single optical multiplexed data stream. At the receiver side, this optical data stream is divided into different colors or wavelengths by using color filters and then by using photo detectors and hence, their respective data are decoded. Due to WDM data is transmitted in parallel form so the higher data rate can be achieved. In this paper, a WDM-based VLC system is demonstrated on Opti-System software. The achievable data rate is up to 100 Mbps with the maximum bit error rate of 5.3 × 10−8 which is less than the pre-forward error correction limit i.e., 3.8 × 10−3.
