研究目的
Investigating the performance of a bidirectional WDM-PON using FTTH architecture for high bandwidth demand and as a solution to the last mile problem.
研究成果
The proposed bidirectional WDM-PON with FTTH architecture demonstrates improved performance in terms of Q-factor and BER, making it a viable solution for high bandwidth demand and the last mile problem. The system supports triple-play services and offers a significant upgrade over existing DSL and CATV networks.
研究不足
The study is limited to simulation results and does not include physical implementation or testing under real-world conditions. Potential areas for optimization include further increasing the bit rate and extending the transmission distance.
1：Experimental Design and Method Selection:
The study involves designing a bidirectional WDM-PON with FTTH architecture using EDFA, WDM mux-demux splitter, and APD photo detector for a 3 Gbps NRZ transmission system over 30 km of optical fiber.
2：Sample Selection and Data Sources:
The system is simulated for different areas (hospital, business, residential, school-mall, building) with varying distances from the main splitter.
3：List of Experimental Equipment and Materials:
Equipment includes EDFA, WDM mux-demux splitter, APD photo detector, and optical fiber cable.
4：Experimental Procedures and Operational Workflow:
The system is simulated using Optisystem 7 software to analyze performance in terms of Q-factor, BER, and eye diagrams.
5：Data Analysis Methods:
Performance is evaluated based on Q-factor and BER, with comparisons made to existing literature.
