摘要
优化设计了色散补偿拉曼放大器,并将其应用于城域网络中,测试了系统的各项性能,包括光缆的实际衰减,发送端和接收端各点的光功率,拉曼放大器的实际增益,系统极限接受灵敏度,短期和长期误码率,应用前后线路的稳定性,以及不同拉曼放大器抽运功率下可达到的无中继传输距离。在使系统具有高稳定性的前提下,最大无中继传输距离可达到215 km,取得了较好的试验效果,并由此得出光纤拉曼放大器在长跨距的光纤传输系统中有很好的应用前景。
The optimized dispersion compensation distributed fiber Raman amplifier is designed and used in Metropolitan Area Network system. The characteristics including the attenuation of the fiber, output and the receiving power, the utmost receiving sensitivity, Raman gains are tested. The maximum transmission distance arrived at 215 km. The results show that Raman amplifier has good prospects in long distance communication system .
