“…The (quality factor of 6 or BER of 10e−9) is adopted as a communication condition in this work. According to the results, the communication distance is decreased as the atmospheric loss is increased, this agree with results in the literature (Yaseen et al 2020 , 2021 ; Abdulsatar et al 2021 ). The maximum obtained range is about 1.3 km with the clear weather, the link distance degraded with the increasing in the attenuation to reaches to 0.675 km at foggy weather.…”

In this work, the performance of wavelength division multiplexing based radio over free space optics (WDM-RoFSO) communication system is investigated utilizing OptiSystem 0.7 software. Four weather conditions are adopted in this paper, namely, clear, haze, rain and fog with attenuation losses of 0.2 dB/km, 2.3 dB/km, 4.3 dB/km and 8 dB/km, respectively In addition, a high radio frequency of 30 GHz with high bit rate of 160 Gbps is modulated and carried on optical signal for fifth generation (5G) applications. The dual channel technique is employed in order to enhance the performance parameters of proposed WDM-RoFSO communication system. The enhancement in the link range is about; 46.1%, 35%, 29.4% and 25.9% for clear, haze, rain and fog, respectively.

“…The FSO-link is assumed as an stand by solution for FO-link when; 1) the FO-link installation become very costly, impracticable, or unattainable to install [1], [2], 2) the FO-link is collapses as a consequence of a bombing during wars or natural disaster [3], 3) there is a tra c issue on the rst mile or last mile of the FO-link [4]. As a result, the integration of FO-link and FSO-link to build a hybrid communication system has received a lot of attention in the last decade [3]- [10].…”

The simulation and investigation of a 32×10 Gb/s WDM all-optical bidirectional hybrid communication system for outdoor applications is presented in this article via multidisciplinary softwares. In order to track the system condition, a strain sensor based on ber Bragg grating (FBG) is integrated in-line with the ber optic link (FO-link). Then, a free space optical link (FSO-link) with 4-channel is simulated to act backup or rescue to the FO-link in the event of disaster or bombing. The FO-link is working well until the strain reach to 180 µε, after that the FO-link has degraded. Therefore, an optical switch is incorporated in between these systems (FO-link & FSO-link) to turn-on the FSO-link which act as a backup system to FO-link and maintains the continuity of the data transmission. According to the hybrid link results, there is an e cient enhancement in the Q-factor as compared with the FO-link even when there is heavy rain.

“…The LOS is a highly secure, easy‐to‐deploy, and license‐free application, whereas fiber optic implementation tends to be difficult 3 . Due to geographical location, extreme information transfer with increased data rates, and exposure to electromagnetic (EM) intrusion, the implementation process tends to be complex 4,5 . Sixth‐generation (6G) wireless communications have been the focus of recent studies since they will be employed in the near future.…”

SummaryIn the case of future access networks, such as 6G‐based applications, the free‐space optical communication (FSO) technology is an efficient solution. FSO in 6G is extremely popular because of its unique properties, which include ease of installation, high bandwidth, high security, license‐free long range, and interference resistance. However, environmental disturbances have a negative impact on the FSO system's functioning. Because of these atmospheric turbulences, the optical information gets restricted, which in turn reduces the link reliability, power density, and distance. This paper proposes a hybrid FSO strategy for improving system efficiency to address these problems. Signal creation is fundamental to every successful communication system. The FSO system consists of three components: the transmitter, the channel medium, and the receiver. The transmitter section includes a continuous wave laser, a Mach–Zehnder modulator, a nonreturn to zero transpose Walsh code generator, and a nonreturn to zero pulse generator. Wavelength division multiplexing‐optical code division multiple access‐spectrum slicing (WDM‐OCDMA‐SS) is used to facilitate efficient data transfer after signals have been generated by alternate mark inversion (AMI). In order to boost a weak signal, fused Raman erbium amplifiers (Fuse‐RE) are used. Q factor and log bit error rate (BER) are used to assess the performance of the suggested approach. The proposed model has obtained a log BER of −15.3291 for clear air and a Q factor of 8.2922, whereas the performances are implemented using Python. The proposed approach achieves better performance when compared to the existing methodologies.
