Abstract: This research is of combining Passive Optical Network (PON) with Optical Wireless Communication (OWC) using Wavelength Division Multiplexing (WDM) transmitter for PON. For optical wireless communication, Light Emitting Diode (LED) and converging lens with Positive Intrinsic Negative Photo Detector (PIN-PD) is combined. To enable high speed transmission, low attenuation and flexible multiple access with simplified Optical Network Unit (ONU) intensity modulation is used with operating wavelength of 1550 nm. The system successfully delivers a distance of 500 cm wirelessly indoor after transmitting over a span of 25 km using a standard Single Mode Fiber (SMF) together with eight wired users. To overcome the distortion that occurs when the signal travels over a long distance, low pass Bessel filter and 3R-Regenerator is used to reshape the distorted signal. The 1×8 optical splitter is used to support eight users. This system can achieve a maximum data rate of 622 Mbps at each direction. The measured Bit Error Ratios (BERs) for each user are all smaller than the 7% pre-Forward-Error-Correction (pre-FEC) limit of 3.8×10-3 which shows the promising potential and feasibility of this proposal to extend multiple services from metro areas to suburban areas
