摘要: 采用了节点隔离的均衡原则,提出了用可调谐衰减器对波长信道功率调节的两种方案,实验和数值计算表明这两种调节方案容易使各个信道功率差在1 dB以内.并在此均衡方案下对网络性能进行了数值分析,计算结果表明,通道设置功率和线路的衰减量对网络规模都有较大的影响.

关键词: 信道均衡, 增益不平坦性, 节点隔离原则

Abstract: The two methods of node equalization is proposed using tunable attenuator based on the equalization principle of node isolation. The range of 1 dB is easily realized by the experiment. The numerical analysis shows that both the path power set in advance and the attenuation on the line will affect the scale of networks.

Key words: channel equalization, imbalance of gain, principle of node isolation
