Time and wavelength division multiplexing passive optical network (TWDM-PON) is adopted across the globe and is considered as the most remarkable trend of the next-generation solution to serve exponential traffic growth for fifth-generation (5G) network. In the interest of achieving 5G network requirements, we propose a mode division multiplexing (MDM) based bidirectional 40/40 Gbps hybrid TWDM-PON and free-space optics (FSO) system. The system performance is analyzed for bidirectional hybrid fiber/FSO channels incorporating four distinct Laguerre-Gaussian (LG00, LG01, LG11, and LG21) spatial modes for variable fiber (10-155 km)/FSO (10-1000 m) link ranges and different receiver aperture diameters (20 μm-60 cm). Based on Gamma-Gamma (GG) modeled FSO channels using Laguerre Gaussian modes, bit error rate (BER) performance of the system is numerically investigated under the impact of dynamic atmospheric weather conditions, weak-to-strong turbulence conditions, pointing errors, and geometric loss (GL) at an acceptable BER of 10 −9. In addition, to support the numerical analysis, the simulation results exhibit that the hybrid fiber/FSO LG00 signals over 1000 m FSO and 155 km fiber link ranges are successfully transmitted in the system with 40 μm spatial and 60 cm FSO receiver aperture diameters under the impact of strong turbulence, atmospheric attenuation of 0.2 dB/km and noise. Moreover, the performance comparison of the MDM-based hybrid TWDM-PON/FSO with the previous latest literature works reveals a superior system performance under practical environment conditions. The proposed work can be utilized to realize longreach, bandwidth-efficient, high-capacity, and high-speed data transmission links.

“…Recently, OFDM-based radio over free-space optics have proposed and they have shown attractive linkdistance enhancement on different atmospheric conditions, [26,27]. However, both multiplexing to enhance the data rate and using low order modulation to enhance the reliability have the drawbacks of higher processing time and lower data rate, respectively, for future communications, 5G.…”

Free Space Optics (FSO) communication provides attractive bandwidth enhancement with unlicensed bands worldwide spectrum. However, the link capacity and availability are the major concern in the different atmospheric conditions. The reliability of the link is highly dependent on weather conditions that attenuate the signal strength. Hence, this study focuses to mitigate the weather and geographic effects using iterative optimization on FSO communication. The optimization maximizes the visibility distance while guaranteeing the reliability by minimizing the Bit Error Rate (BER). The wireless optical communication system is designed for the data rate of 10 Gbps. The performance of the proposed wireless optical communication is compared against the literature in terms of visibility distance, quality factor, BER, and Eye diagram at different atmospheric conditions. The simulation results have shown that the proposed work has achieved better performance.
