“…DUTTA et al studied the hybrid orbital angular momentum and wavelength division multiplexing (OAM-WDM)-based FSO system to realize 100 Gb/s FSO links over 3.2 km under clear weather, haze, rain, and fog weather conditions. A very low BER of 5 × 10 -9 and a good quality factor (Q) of 5.4 are obtained for a 2.4 dB power penalty [12]. A 640 Gb/s data transmission over 180 m link distance is demonstrated by multiplexing of 4 OAM modes in FSO system.…”

To meet the needs of future wireless optical networks, this paper introduces a high-speed, hybrid multiplexed, coherent free-space optical (FSO) communication system that integrates an orbital angular momentum (OAM) multiplexed signal with an orthogonal frequency division multiplexing (OFDM) technique. Two independent QAM polarized beams, each carrying in-phase and quadrature (I/Q) phase 16-QAM-OFDM modulated data, are combined using mode division multiplexing (MDM) to increase the capacity of the proposed system. The reason of choosing OFDM is its capability to support higher data rate, and mitigating intersymbol interference (ISI). The signal is detected using a coherent detection-based digital signal processing (DSP) algorithm at the receiver end. The proposed hybrid FSO system is evaluated in low and heavy dust environments using bit error rate (BER), link distance, optical signal-to-noise ratio (OSNR), and received optical power performance matrices. The simulation results demonstrate the successful transmission of a 120 Gb/s single carrier over the longest link ranges of 1.5 and 0.40 km, respectively, under low and heavy dust weather environments below the signal degradation threshold value (forward error correction (FEC) limit) of BER 2.2 × 10–3 in strong turbulent conditions.

“…17 The experimental demonstration of vector SDM to transmit 228-Gbit/s information over 80-cm FSO link using optical frequency comb is reported in Zhang et al 18 The work in Liang et al 19 reports four-channel hybrid WDM-SDM transmission in FSO link employing Laguerre-Gaussian (LG) and Hermite-Gaussian (HG) modes and nonreturn to zero (NRZ) modulation; 40-Gbit/s data transmission for 440-1200 m range for varying atmospheric conditions is achieved. A 100-Gbit/s hybrid orbital angular momentum (OAM) multiplexed-WDM FSO transmission for range varying from 500-3200 m is reported in Dutta et al 20 The work in Singh et al 21 reports 40-Gbit/s FSO transmission for range varying from 64 to 800 m by employing OAM multiplexing with NRZ signals. In another work, 22 120-Gbit/s FSO transmission for 150-300 m range by employing optical code division multiple access (OCDMA) and OAM multiplexing is reported.…”

Summary A high‐capacity free‐space optics‐based terrestrial communication link using spectral‐efficient space division multiplexing and polarization division multiplexing techniques has been proposed in this research work. Orthogonal frequency division multiplexing with the use of coherent detection has been proposed for the transmission of quadrature amplitude modulated high‐speed signals. Eight independent 50‐Gbit/s data streams are transported by two orthogonal polarization states (X and Y) of four distinct Hermite–Gaussian spatial modes to increase the transmission rate of the link to 400 Gbit/s over a single channel. Through numerical simulations, we report feasible transportation of 400‐Gbit/s information at 10 km under clear weather with faithful performance. Further, the impact of atmospheric scintillation and fog weather has been evaluated using simulations. The results report that the maximum range reduces to 6 km under clear weather in the presence of strong atmospheric scintillation. Moreover, the maximum range of 2000, 1700, and 1300 m is reported for light, moderate, and heavy fog conditions respectively.
