Abstract
A 32 GHz radio-over-fiber (RoF) system using integrated mode division multiplexing (MDM) and optical code division multiple access (OCDMA) scheme is realized. Quad orbital angular momentum (OAM) based zero cross-correlation OCDMA coded signals with time division multiplexing are transmitted over hybrid fiber-free space optics (FSO) link under the impact of clear air, haze, light, and moderate fog conditions. Simulation results depict that the system offers a maximum 0.1 km fiber and 500 m FSO range at aggregate 30 Gbps throughput. Also, the system offers acceptable bit error rate performance with a maximum 14 μm spot size, 14 cm transmitter/receiver aperture diameters, and a minimum received power of −2 dBm. Compared to existing designs, this work offers optimum system performance.
