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.

Abstract Communication networks are forced to transition to optical access networks in order to boost the information rate of transmission due to huge utilization of internet. Passive optical networks (PONs) are a highly developed and promising technology that offers low cost design, high bandwidth, and information rate for both residential and commercial use. PON uses the passive components incorporating couplers, splitters, as well as combiners. Compared to modern access networks, PON features bidirectional capabilities, cost-effectiveness, high resource efficiency, transparency, privacy, flexibility, along with upgradeability. Due to these ever increasing demands for high bandwidth, high capacity, and long reach communication for next generation networks, next generation passive optical networks (NG-PONs) are optimum choice. It provides cost-effective, energy efficient network architecture and can be realized in integrated wired/wireless network scenarios for fronthaul/backhaul data transmissions. This paper reviews the standardization process of PON that led to the development of the NG-PON. The detail literature review of various technologies related to PON and NG-PON has been conducted. Potential drawbacks of NG-PON as well as the advantages and disadvantages of various strategies are also discussed besides the future scope. Meanwhile it offers long haul high bandwidth hybrid scenarios. The futuristic PON networks may be realized for high undersea, satellite, and beyond sixth generation (6G) networks.

Also, Flat ball GEPON architecture permits 9 and 10 dBm energy saving in downlink as well as uplink, respectively, than conventional GEPON architecture at 1 ms delay. The proposed architecture with 50 Erlang load allows energy ratio of 39% in downlink and 37% in uplink, at 25 × 100 Gbps traffic rate for 55 nodes. Besides this, the faithful fiber range of 100 km considering fiber no‐linearities and impairments can be obtained successfully.

With a threshold bit error rate (BER) of 10−3, the results demonstrate reliable transportation over a 100 km fiber at −17 dBm received power and in a maximum LiFi range of 20 m. Furthermore, the system offers symmetric 4 × 50 Gbps transmission rates under the impact of fiber–LiFi channel impairments with maximum irradiance and incidence half-angles of 500.

An approach is presented to enhance the isolation of a two-port Multiple Input Multiple Output (MIMO) antenna using a decoupling structure and a common defected ground structure (DGS) that physically separates the antennas from each other. The antenna operates in the 24 to 40 GHz frequency range. The innovation in the presented MIMO antenna design involves the novel integration of two arc-shaped symmetrical elements with dimensions of 35 × 35 × 1.6 mm3 placed perpendicular to each other. The benefits of employing an antenna with elements arranged perpendicularly are exemplified by the enhancement of its overall performance metrics. These elements incorporate a microstrip feed featuring a quarter-wave transformer (QWT). This concept synergizes with decoupling techniques and a defected ground structure to significantly enhance isolation in a millimeter wave (mm wave) MIMO antenna. These methods collectively achieve an impressively wide bandwidth. Efficient decoupling methodologies have been implemented, yielding a notable increase of 5 dB in isolation performance. The antenna exhibits 10 dB impedance matching, with a 15 GHz (46.87%) wide bandwidth, excellent isolation of more than 28 dB, and a desirable gain of 4.6 dB. Antennas have been analyzed to improve their performance in mm wave applications by evaluating diversity parameters such as envelope correlation coefficient (ECC) and diversity gain (DG), with achieved values of 0.0016 and 9.992 dB, respectively. The simulation is conducted using CST software. To validate the findings, experimental investigations have been conducted, affirming the accuracy of the simulations.

This paper proposes a new design of leaky wave antenna (LWA) based on substrate integrated waveguide (SIW) technology for THz applications. The suggested LWA structure has a combination of longitudinal and transverse slots and makes a 10-element linear array of radiating elements. To address the problem of open-stop-band (OSB), four additional smaller slots were etched on the corners of longitudinal and transversal slots. At the broadside, this LWA provided a gain of 12.33 dBi, and a continuous wide beam scanning range from +78° to −6° via the broadside while exhibiting efficient radiation performance over the operating frequency bands of 105 GHz to 109 GHz with a peak gain of 16.02 dBi.

In recent years, optical wireless communication has promised several benefits over radio frequency communication in atmospheric, deep space and underwater communications. Satellite-to-underwater communication technology can be applied to commercial, naval, scientific and engineering operations because of its high data rate, high security, long-reach and low cost. In this paper, a high-speed, long-reach integrated free space optics (FSO)-passive optical network (PON) system using non-orthogonal multiple access visible light communication (NOMA-VLC) is proposed. It poses a 10/2.5 Gbps per channel bit rate for satellite-to-underwater applications. Numerically calculated results provide the splitter power budget of −35 dBm in the downlink and −32 dBm in the uplink. Additionally, a receiver sensitivity of 23 dB in the downlink and 10 dB in the uplink direction can be obtained in the system using a modified new zero cross-correlation (MNZCC) code under clear environment conditions. Again, the simulative analyses indicate that the suggested system supports 290 underwater devices successfully and offers a high 10 dBm signal-to-noise ratio over 10 km FSO, 100 km fiber and 5 m VLC range. Moreover, it provides a signal-to-noise ratio of 39 dB, with −9 dBm received optical power at 300 fields of view under fiber-wireless channels’ impairments. We argue that the suggested system is a symmetric system adapted to different link distances and which offers improved receiver sensitivity and high received optical power at a 10−9 bit error rate (BER). The comparative analysis shows the advantages of the suggested system over previously reported works.

Wheel-based network resilience passive optical network (PON) based on mode division multiplexing (MDM) can be integrated with optical code division multiple access (OCDMA) schemes efficiently for the fixed and backhaul traffic under normal and break/failure fiber operating conditions. In this work, a bidirectional 10/2.5 Gbit/s hybrid MDM-OCDMA-PON system using multi-weight zero cross-correlation (MWZCC) code is proposed. Donut modes 0 and 1 are incorporated by the MDM technique in the proposed system. The benefit of this work is to offer an inexpensive, high-bandwidth and advanced long-haul network with satisfactory resource utilization ability for fiber links with protection against faults and to improve the reliability along with survivability of the network. The simulation results show the successful realization of the multimode fiber (MMF) link at 1.6 km in the uplink and 1.2 km in the downlink directions under an acceptable bit error rate (BER). The minimum accepted received power of −31 dBm in uplink and −27 dBm in downlink over 1 km link at 10/2.5 Gbit/s rate is obtained. Moreover, the minimum received power of −20 dBm in uplink and −30 dBm downlink is achieved by using MWZCC code compared to other codes handling 58 simultaneous end users. Further, the influence of fiber impairments and connected devices on the proposed approach is numerically evaluated. Moreover, it is shown that the wheel based proposed approach performs well than other topologies for the bidirectional network resilience transmission.

AbstractIn this paper, a hybrid time and wavelength division multiplexing passive optical network (TWDM‐PON) and wavelength division multiplexing optical code division multiple access (WDM‐OCDMA) with free space optics (FSO) for bidirectional 160/40 Gbps transmission has been proposed. Also, to offer the information to 64 users over 60 km fiber and 600 m FSO channels under diverse climate conditions have been presented. Also, to resist the fiber impairments, interference, noise and losses under the effect of unfavorable climate conditions in hybrid fiber‐FSO link, a modified new zero‐cross correlation (NZCC) code is effectively used in the system to enhance the system ability to access shared bandwidth with users' security. The performance of the designed PON system has been analysed and investigated for diverse FSO (10–600 m) and fiber distance (0–60 km) under distinct climate conditions. Based on mathematical and simulation analysis, the designed system using modified NZCC code is shown to provide better performance than other OCDMA codes. The designed system with hybrid fiber‐FSO link improves the performance of the system in terms of high received optical power of 3 dBm and support 110 users simultaneously at acceptable BER of 10−9, under fiber impairments, climate conditions and turbulences. Additionally, on comparing the designed system's performance with the prior latest work in literature reveals its superiority than others in codes and system design.

This research paper introduces a concept for photo compression that utilises the spatial redundancy approach. The proposed method use the discrete cosine transform technique with various block sizes, specifically 8x8, 16x16, 32x32, and 64x64. The process of quantization can be achieved by establishing a set of threshold values at various distances. Due to these aforementioned considerations, the implementation of this strategy is straightforward, requiring less memory usage and may be completed in a shorter duration. The utilization of the Discrete Cosine Transform (DCT) methodology was employed to develop and execute a compression approach for virtual graphics through the utilization of MATLAB. The calculation of the compression ratio and peak signal-to-noise ratio was performed for each compressed block to get the ideal results. In order to enhance the analysis of the collected data, utilized the metrics of Compression Ratio (CR) and Peak Signal-to-Noise Ratio (PSNR), in conjunction with software tools that are applicable across several sectors.
