The demand for Internet network services will continue to grow as the population increases. With this growth, there is a greater need for increased bandwidth. This paper discusses a proposed design of an XGS-PON (10 Gigabit Symmetrical Passive Optical Network) FTTH access network for Pesona Kahuripan 3, Bogor, West Java, including calculations and analysis of the link power budget, rise time budget, BER, and Q factor to assess the viability of the proposed design. The design considers a cascade of high split ratios in ODC and ODP to increase user capacity. The result shows that the proposed FTTH design achieved all parameters in splitter ratio 1:256 with the received power of -24.090 dBm and -23.803 dBm for uplink and downlink, respectively, higher than the minimum required value of -29 dBm. The rise time system for uplink is 0.264 ns, and for downlink it is 0.265 ns, which is lower than the NRZ requirement value of 0.7 ns. BER for upstream is 2.93 × 10 -15 , and for downstream it is 2.274 × 10 -18 , which is lower than 10 -9 . These results indicate that the proposed network can be implemented using a high splitting ratio of 1:256.

The advancement toward fifth-generation (5G) networks heralds a transformative era in the mobile sector, poised to revolutionize various intelligent automation applications and the Internet of Things (IoT), With its rapid connectivity and minimal latency, 5G is a crucial driver for innovations in IoT, AI, autonomous vehicles, virtual reality, and beyond. Millimeter wave (mmWave) technology is emerging as a key enabler for 5G, offering high-capacity, high-mobility, and long-range communication capabilities. Among the potential of 5G, Radio over Fiber (RoF) technology emerges as a solution to address the demands of 5G by seamlessly integrating wireless communication with optical fiber transmission systems, offering bandwidth, transmission capacity, and economic benefits. Evaluating critical parameters such as the Q factor, bit error rate (BER), and signal-to-noise ratio (SNR) over optical spans up to 20 km, the study highlights the importance of semiconductor optical amplifier integration (SOA). The incorporation of SOA as a post-amplifier enhances signal robustness, improving Q factor and BER while managing SNR, ultimately meeting ITU standards, and ensuring signal integrity in 5G environments.

telecommunication technology is one technology that continues to grow and improve. In order to keep up with the advancement, an improvement of the existing Fiber Free Space Optic is necessary. This research offers an improved design of the Fiber-Free Space Optic by adding a new method and improving several areas of amplifications. This research considers the use of the Fiber Bragg Grating (FBG) module to compensate for loss of performance of the system, especially for long-distance usage. The FBG module in theory will reflect the necessary wavelength. This paper also involves finding better strategic locations to implement optical amplification modules, including EDFA. Both of the module used commonly used in the optical communication network buat haven't been maximised int he Fiber-FSO hybrid communication network setup. The proposed design reaches 10 km of FSO range with 1 dB/km of attenuation and 10 km of fiber range on both sides of the transmitter and receiver. The performance of the design will be measured by the Q factor and the minimum BER parameters. The proposed design achieved the value of the Q factor above 9, and the BER minimum well above 10- 20 • This paper will present the data through tables extracted from the simulation device and graphs gathered from the data. With the improvements, the design proposed in this research achieved an astonishing result in both the range of the system and the performance of the system. Good performance in the network proposed indicates the ready-ness of a hybrid Fiber-FSO setup usage especially when implemented in a metropolitan city.

Digital transformation requires significant high data rate transmission for broadband access, including optical fiber networks. Increasing the data rate is a technique to provide more capacity linearly; however, its major challenge is dispersion, which limits its capacity in shorter distances. This research proposed an optical network design with a bitrate observation of 64 Gbps for downstream and 50 Gbps for upstream in a four-channel passive optical network applying the dispersion compensation fiber (DCF) to compensate for the dispersion of a 1:64 splitting ratio and optimizing variables of channel spacing and WDM multiplexer bandwidth. The results show that the compensating component improves the Q factor, indicating that dispersion can be suppressed, while optimization of the WDM multiplexer bandwidth can potentially enable high data rate transmission over 40 km for both downstream and upstream. However, the downstream performance is still lower than the considered threshold of six up to 40 km, and further investigation is necessary to achieve the expected upstream performance.

This study discusses the Wavelength Division Multiplexing-based Free-Space Optics (WDM-FSO) communication system over HAPs for 5G applications. It aims to evaluate the potential of this system in meeting the need for reliable 5G connectivity. Through simulations using OptiSystem, the research explores the implementation of HAPs with a focus on uplink connectivity between ground stations and HAPs. The study examines the influence of line coding, transmission power, atmospheric conditions, and altitude on the Log-Bit Error Rate (Log-BER) and system quality factor (Q-Factor). The results show that RZ line coding is effective in altitude variations, while NRZ is better in weather variations. Power variations do not show significant changes in line coding. This research illustrates the potential of WDM-FSO technology on HAPs to support reliable wireless connectivity in the future.

The demand for fast, reliable, and adaptable communication solutions has led to increased interest in wireless technologies. Free-Space Optical (FSO) communication systems with the integration of FSO with High Altitude Platforms (HAPs) presents unique opportunities for enhancing connectivity. However, challenges arise in optimizing system performance amidst varying altitude and weather conditions. This paper conducts a thorough comparative evaluation of line coding schemes for uplink transmission in FSO-HAP systems across diverse scenarios using OptiSystem. Results indicate NRZ as the top performer, excelling in both single-channel and Wavelength Division Multiplexing (WDM) setups due to its simplicity and spectral efficiency. RZ demonstrates optimal performance, particularly in WDM systems spanning up to 50km, while NRZ and RZ emerge as preferred options for long-distance optical communication. The Q-Factor for single channels recorded 39.067 for RZ and 59.926 for NRZ. Meanwhile, the average Q-Factor for WDM channels is 14.667 for RZ and 7.245 for NRZ. Caution is warranted in HAPs deployment, as current capabilities may be insufficient, particularly under adverse weather conditions.

This research study uses a radio over fiber at 28 GHz for a 5G fronthaul design that uses a single channel without and with amplification. For a 20 km distance, the downstream Q factor has not yet met the standard at 3.37, while upstream, it has increased to 10.76. The results show that the power received increases when an amplifier is used, but the Q factor and BER are not significantly improved. It shows that in this scheme, the dispersion factor is more dominant in influencing data transmission than the power level. From the current results, some issues can be further researched, such as dispersion compensation to improve the data transmission quality and suppress unwanted harmonic frequencies.

The demand for a better and more capable telecommunication system continues to increase as other technologies advance. telecommunication systems are facing a major problem in order to achieve higher capacity. To address this problem, a more capable system with higher capacity, yet reliable is required. This research offers a solution to this problem by improving the Fiber-FSO system using WDM technology. The key is to achieve larger capacities using multiple canals in the WDM method. This research proposes the usage of the 4 canal WDM component (193.1–193.4 THz) for the Fiber-FSO system. The design of the WDM Fiber-FSO system using EDFA and FBG proposed in this research reaches up to 80 Gb/s of data rate. This result is significantly higher when compared to other regular Fiber-FSO systems. One of many implementations of this system is the interbuilding communication system. For this implementation, a long-range system is necessary. This research provides an interbuilding communication system with fiber optic range extending up to 10 km per side and FSO media range reaching up to 10 km. The performance of the system will be measured mainly using the Q factor and minimum BER. At normal attenuation of 1 dB/km, the proposed design system reaches the best result averagely when given 10 dBm of power input. The average performance result in this scenario reaches Q Factor 6.78 on average. This performance result is in accordance with the standard given for the proposed design with the Q factor that requires the value of 6. The proposed design will be tested in several weather conditions in metropolitan cities, with attenuation in the FSO media reaching 20 dB/km for the worst conditions. The result of the design test under several conditions shows that the system will need to sacrifice the FSO media range as conditions worsen to achieve acceptable results.
