研究目的
Investigating the performance of a 40 Gbps UV communication system based on DWDM technology to overcome the limitations of low rate and limited range due to atmospheric transmission attenuation.
研究成果
The 40 Gbps UV communication system based on DWDM technology shows promising performance with a maximum transmission distance of up to 1200 meters at 40 Gbps without compensation. The system's performance is influenced by transmission distance, power, communication rate, atmospheric visibility, and divergence angle. The simulation results provide valuable insights for the design of UV communication systems.
研究不足
The study is limited by the simulation environment and does not account for all real-world atmospheric conditions. The performance is also limited by the device capabilities, such as the maximum transmitting power of UV lasers.
