Investigation of WDM-EPON Integrated with Optical Wireless Channel for 5G Optical Communication

With the advancement in communication systems, there is a need for large bandwidth to send more data at a higher speed. Wavelength division multiplexing (WDM)-ethernet passive optical network (EPON) is important due to its efficiency, higher bandwidth, low-cost passive connection, and reduced complexity of deployment and maintenance of the network. The implementation of radio over fiber in wireless communication achieved a high data rate and high capacity due to the utilization of high-capacity optical fiber and the flexibility of wireless networks. Optical wireless channel (OWC) is the technique in free-space optical communication, which is a high-speed and large-capacity type of communication system. It uses infrared light to convey message from transmitter to receiver. OWC is the solution to the last mile problem, mainly in overpopulated urban areas. This paper demonstrated the integration of OWC and WDM-EPON technology that makes the system more advanced and cost-effective, with high BW and high data rate. The results analysis is based on bit error rate (BER), quality factor (Q Factor), and eye pattern. The system has been analyzed using different power source values, different lengths, and different operating wavelengths. The results for OWC have shown that 2.5 Gbps is better than 5 and 10 Gbps.
