Introduction to DWDM System and Optical Amplifiers

In the current digital era, the need for information distribution is increasing along with the increase in the number of users. Communication technology is also experiencing rapid development, where optical fiber is the first choice to meet this demand. One of the important innovations in optical fiber technology is Dense Wavelength Division Multiplexing (DWDM), which allows data transmission in large quantities through one channel. However, the DWDM system often decreases in signal power, so optical amplifiers such as SOA (semiconductor optical amplifier), EDFA (erbium-doped fiber amplifier), and amplifier raman to overcome this problem. One interesting method is the use of hybrid optical amplifiers (HOA) which combines several types of reinforcers.

Optical Amplifiers in DWDM System

Optical amplifiers play a crucial role in the DWDM system, as they help to amplify the signal power and maintain the quality of the transmitted data. There are several types of optical amplifiers, including SOA, EDFA, and Raman amplifier. Each type of amplifier has its own strengths and weaknesses, and the choice of amplifier depends on the specific requirements of the DWDM system.

Hybrid Optical Amplifiers (HOA)

One of the innovative methods used in the DWDM system is the use of hybrid optical amplifiers (HOA). HOA combines several types of optical amplifiers to provide a more efficient and effective amplification of the signal power. The use of HOA has several advantages, including improved signal quality, increased capacity, and reduced noise.

Implementation of Optical Amplifiers in DWDM System

The implementation of optical amplifiers in the DWDM system has a major effect on performance. There are three main positions commonly applied: Booster amplifiers, Inline Amplifiers, and Pre amplifiers. In this study, we will discuss the analysis of the comparative performance of the Hybrid SOA-EDFA and Raman-EDFA optical reinforcement in the DWDM system.

Simulation Results and Analysis

The test was carried out using Optisystem 7.0 software, with a focus on the analysis of the Q Factor and Bit Error Rate (BER) values on the length of the cable varies between 30 to 250 km with a bitrate 2.5 Gbps. The research scheme includes three configurations, namely Booster-Inline Amplifiers, Booster-PRE amplifiers, and Inline-PRE amplifiers for each type of hybrid amplifier. This study produced 24 iterations, which offer in-depth insights about the performance of each configuration.

The simulation results show that the best performance is obtained from the Raman-EDFA hybrid optical amplifier with the Raman Booster-EDFA Inline configuration. In this configuration, the Q factor value reached 246.02 for 8 canals, with 0, and for 16 channels, the maximum Q Factor value recorded is 196,208 with BER 0. This shows that the reinforcement reduce data quality.

Comparison of Performance of Hybrid SOA-EDFA and Raman-EDFA

The comparison of performance of Hybrid SOA-EDFA and Raman-EDFA optical amplifiers shows that the Raman-EDFA hybrid optical amplifier provides better performance than the Hybrid SOA-EDFA. The Raman-EDFA hybrid optical amplifier has a higher Q factor value and lower BER value, which indicates that it provides better signal quality and reduced noise.

Conclusion and Future Work

With optimal signal reinforcement, the DWDM system that uses Raman-EDFA reinforcement not only promises better performance, but also increases the efficiency and capacity of the communication network. This is very important in the context of network needs that continue to develop, where the delivery of fast and accurate information is a top priority. This study made an important contribution to the development of future communication technology, as well as highlighting the potential for the use of hybrid optical reinforcement in the DWDM system.

Recommendations for Future Research

This study provides a clear picture of the effectiveness of optical reinforcing positions in improving the performance of the DWDM system. However, there are still many areas that require further research and development. Some of the recommendations for future research include:

Investigating the use of other types of optical amplifiers, such as SOA and Raman amplifier, in the DWDM system.
Developing new hybrid optical amplifiers that combine different types of optical amplifiers.
Investigating the use of optical amplifiers in other types of communication systems, such as WDM and CWDM.

Conclusion

In conclusion, this study provides a comprehensive analysis of the comparative performance of Hybrid SOA-EDFA and Raman-EDFA optical amplifiers in the DWDM system. The results show that the Raman-EDFA hybrid optical amplifier provides better performance than the Hybrid SOA-EDFA. This study highlights the potential for the use of hybrid optical reinforcement in the DWDM system and provides recommendations for future research and development.
