研究目的
Investigating the minimization of Four Wave Mixing (FWM) effect in long-haul DWDM optical fiber communication systems to enhance signal quality.
研究成果
The research demonstrates that increasing dispersion coefficient and using dispersion compensated fiber can effectively mitigate FWM effects in DWDM systems, improving signal quality. Optimal performance was achieved with a bandwidth of 20 GHz and lower optical power of -5 dBm.
研究不足
The study is limited to a specific setup of 70 km fiber length, 3 channels, and 10 Gbps bit rate. The effectiveness of dispersion compensation and FWM mitigation techniques may vary with different system configurations.
1：Experimental Design and Method Selection:
The study uses increasing dispersion coefficient techniques and dispersion compensated fiber to mitigate FWM effects. The performance is evaluated based on Bit Error Rate (BER) and Quality factor (Q-factor) using Optisystem (version-16) software.
2：Sample Selection and Data Sources:
The system is a 70 km fiber length DWDM system with 3 channels at 10 Gbps bit rate and 100 GHz channel spacing.
3：List of Experimental Equipment and Materials:
Includes single mode fiber (SMF), Dispersion Compensation Fiber (DCF), erbium doped fiber amplifier (EDFA), and various analyzers.
4：Experimental Procedures and Operational Workflow:
The system setup includes transmitter, fiber, and receiver sections with specific parameters for dispersion, attenuation, and optical power.
5：Data Analysis Methods:
Performance is analyzed based on BER and Q-factor measurements from the simulation.
