“…Stronger is the IR and UV, stronger will be the intensity of signal [22][23][24][25][26][27]. Some other related work similar to the mentioned above has been done by many authors in their manuscripts [13][14][15][16][17][18][19][20][21]. Working in the field of FSO is thus a very appealing option.…”

<p>The field of optics is flourishing day by day on account of the wide usage of the internet and its associated technologies. Free Space Optics (FSO) is a data transmission technique that employs light propagation to send data. This technology is effective in those circumstances where fiber optic cables cannot be deployed. This paper provides a model and simulation of the Fiber Bragg Grating (FBG) based FSO network under different environmental conditions, such as modulation types and data rates. Also, investigation of the impact of Multiple Access Interference (MAI) on FSO under design parameters has been done. The designed system performance is analyzed under the multiuser optical wireless network by changing data rates and modulation types. The proposed model's security is achieved through the use of the FBG encoder/decoder and the FSO channel for transmission. It has been inferred that the CRZ modulation type provides the best BER and Q factor compared to other formats, and a data rate as high as 1Gbps can be achieved using the CRZ modulation format. It has been noticed that as the number of users grows, the BER value begins to deteriorate.</p>

“…For global coverage, FSO systems are assimilated as inter-satellite optical communication systems (Is-OWC). 31,32 FSO transmits data of optical signal through various band frequencies including visible and infrared which are part of unlicensed bands and thereafter, can easily be accessed by every individual without paying any charges to the external telecom agencies which makes it as cost-effective. Since FSO shares the similar transmitter and receiver as required in an optical fiber communication system, the only difference is in its transmission media.…”

The present study examines an interesting wireless system known as spectral/temporal/spatial‐optical code division multiple access‐free space optics (OCDMA‐FSO) by integrating the new three‐dimensional successive weight (3D‐SW) code for the incoherent system. The system is proposed to be adopted in future generations of wireless networks in view of its attractive features such as simple architecture, high data rate, strong immunity against electromagnetic interference, and optimal power consumption. Furthermore, the recommended code has a zero cross‐correlation (ZCC) feature that removes multiple access interference (MAI) and lowers the effect of phase‐induced intensity (PIIN) noise, which primarily affects OCDMA performance. Meanwhile, an original bit error rate (BER) formulation based on the signal‐to‐noise ratio (SNR) calculation has been developed. The computational results clarified that a recommended approach improves optical system efficacy by boosting numerous analytical criteria. Firstly, the numerical outcomes exhibit that the proposed system improves cardinality by 3.67, 3.08, 2.19, and 5 times than the systems using three‐dimensional perfect difference (3D‐PD), both three‐dimensional perfect difference/multi diagonal (3D‐PD/MD) and three‐dimensional‐dynamic cyclic shift/multi diagonal (3D‐DCS/MD), two‐dimensional‐SW, and one‐dimensional‐SW codes, respectively. Further, It saves roughly −7.3 dBm and − 4.2 dBm when moving from (1D) and (2D) to (3D). Second, the implementation of the proposed model under Optisystem software reveals that the system is compatible with optical communication norms and can be used in upcoming generations of wireless networks, where it achieves BER of with better transmission quality reaching 12.09 at a high bit rate until 30 Gbps across a wireless distance up to 6 km.

“…Recently in 2020 [24], authors have demonstrated the transmission of 1.2 Gbps and 1.12 Gbps of data over a 3 and 4 m free space link by using dual polarized green and blue LED-based light streams. On the other hand, hybrid multiplexing schemes are used by many researchers to increase the bandwidth and capacity of optical communication systems [25][26][27][28][29][30][31][32][33][34][35]. In this work, the OOK modulation technique is used for realization of a low-cost VLC system.…”

Visible light communication (VLC) has been proven a promising technology to counter the limitations of radio frequency (RF) communication technology such as high interference and high latency issues. VLC offers high bandwidth as well as immunity to interference from other electromagnetic spectrums. Due to these features, VLC can be an excellent solution for biomedical and healthcare applications for transmission of body sensor signals and other crucial patient information. In this work, a highly efficient VLC system is designed to transmit six channels, with each one carrying 10 Gbps of data, over a 500 m optical fiber link and a 200 cm VLC link. To make the VLC system cost effective, simple and efficient on-off keying (OOK) (non-return to zero) is used as the encoding scheme. Moreover, to further enhance the capacity and bandwidth of the proposed VLC system, hybrid wavelength division multiplexing (WDM) and polarization division multiplexing (PDM) schemes are incorporated by using red, green, and blue lasers. The reported results show the successful transmission of all channels (6 × 10 Gbps) over 500 m optical fiber and 200 cm of VLC link.
