“…OWC technology presents an excellent solution to these challenges. OWC links do not suffer from link failures due to maintenance issues or road digging and are easy to install with lower costs and time requirements compared to optical fiber links (Garg et al 2021;Kumari and Arya 2023). Thus, the motivation behind this work is to develop OWC technology for 5G applications that can sustain reliable and flexible traffic, support intelligent routing design, provide elastic bandwidth, ensure high network efficiency, and offer cost-effectiveness and better system management.…”

Optical wireless communication (OWC) is recognized as a promising technology for future fifth generation (5G) networks. However, limited research efforts have been dedicated to the development of symmetric and bidirectional OWC systems using vertical cavity surface emitting lasers (VCSELs). In this study, we design and investigate a bidirectional 4×10 Gbps VCSEL-incorporated OWC system with an extensive reach, taking into account channel impairments. VCSELs offer high operating power and high reliability, making them suitable for this application. Simulation analyses have been conducted to evaluate the system performance in both the downlink and uplink directions, considering various factors such as noise, geometric losses, and attenuation losses. The results indicate that a maximum OWC range of over 130 km in the downlink direction and 128 km in the uplink direction can be achieved with a link loss of 0.001 dB. The system can tolerate a maximum link attenuation of 2.25 dB/km in the downlink direction and 2.2 dB/km in the uplink direction while maintaining a bit error rate (BER) within the acceptable limit of 10^-9. Additionally, the system demonstrates robust performance at a maximum operating temperature of 348K for VCSELs over a 10 km range at a data rate of 40/40 Gbps. The results further indicate that the maximum values of signal, noise, gain, noise figure, and optical signal-to-noise ratio (OSNR) are-69.68 dBm,-87.65 dBm,-21.14 dB, 21.14 dB, and 82.13 dB, respectively, at a total input power of-69.61 dBm. Comparative analysis with existing studies highlights the superiority of this work over previous efforts, demonstrating significant improvements in system performance and range. This research underscores the potential of bidirectional OWC systems using VCSELs for enhancing future 5G networks.

“…3 Again, with the continuous advancement of internet technologies, there will be a capacity challenge soon; thus, spectrum availability in PONs becomes a major concern. To cope with these limitations, several multiplexing techniques like subcarrier multiplexing, 4,5 wavelength division multiplexing (WDM), 6 as well as orthogonal frequency division multiplexing (OFDM) have been adopted. An OFDM technique owing to its properties of dynamic resource allocation, spectral efficiency, as well as resistance to dispersion in fiber is regarded as a prominent solution to serve the objective of future NGPONs.…”

SummaryThis work presents the bidirectional and symmetric 40 Gbps wheel architecture comprising 16 channels‐based bidirectional hybrid next generation passive optical network with free space optics (NGPON/FSO) system using mode division multiplexing (MDM) scheme. The system incorporates a low‐cost high bandwidth and integrated time and wavelength division multiplexing with orthogonal frequency division multiplexing (TWDM‐OFDM) for data transmission over mixed fiber‐FSO links to various end users at donut modes 0 and 1. This system enhances the fifth generation (5G)‐based networks reliability, survivability, and flexibility, especially in rural places where the core fiber link may be damaged/destroyed under diverse turbulent and weather conditions. The obtained results depict the faithful multimode fiber range of 100 km with fixed FSO range of 100 m at −17 dBm receiver sensitivity and low power penalty of 0.2 dB at 10−9 bit error rate. Maximum FSO range of 2800 m under weak‐to‐strong Gamma‐Gamma turbulence and the effect of fog, rain, snow, and snow with rain can be obtained successfully with fixed 50 km fiber length. Also, the proposed wheel architecture provides superior performance over hybrid ring‐mesh architecture with high split ratio of 1:64. Moreover, the system can sustain up to 70 remote nodes at symmetric 10 Gbps throughput providing high gain, high optical signal‐to‐noise ratio, and low noise figure. The comparative literature work also reveals that the proposed architecture offers high bandwidth, security, long‐reach, and cost‐effectiveness in 5G fronthaul/backhaul networks.
