We propose the visible light communication (VLC) system based on optical access network using white light emitting diode (LED) and reflective semiconductor optical amplifier (RSOA). The RSOA is employed as an optical network unit (ONU) in order to be connected with VLC link based on white LED and photo diode (PD). The proposed architecture is demonstrated experimentally and its performance is verified through the experimental investigation of quality-factor (Q-factor) and eye pattern up to 20 Mb/s data. The variation of performance is shown depending on both the existence of the ambient light and the distance between the LED and PD. A 20 Mb/s downlink and uplink transmission is demonstrated in 23-km single mode fiber (SMF) and 100 cm long wireless channel experimentally.
