WDM-RoFSO transmission: Demonstration based on IEEE 802.11 WLAN standard

We show two experiment setups to verify the applicability of WDM (wavelength division multiplexing)-RoFSO (Radio-over-Free-Space Optics) system: (i) transmission of images files following the data format of IEEE 802.11 wireless local area network; (ii) robust performance analysis of bit error rate for on-off keying signal at a speed of 10 Gbps. Specifically, it is shown that, for 100 m indoor transmission, our testbed satisfies an error-free condition of BER <= 10-12, achieving a total data rate of 20 Gbps. In this paper, we contribute to the evaluation of the practical FSO measurement data by providing experimental measurements. (c) 2022 The Author(s).
