| 摘 要： | 提出一种结构简单、易于实现的正交光标记擦除的新方法.利用频移键控调制产生80 Gbit/s载荷,采用强度调制产生2.5 Gbit/s标记,然后利用电吸收调制器在分组交换网络核心节点处擦除旧标记,再加入新标记实现信息在网络中继续传输.理论分析和数值模拟验证了此方案擦除标记的可行性.

| Abstract: | A scheme of Orthogonal Modulation was studied.FSK was used to produce 80 Gbit/s payloads and IM was used to produce 2.5 Gbit/s labels.Using EAM to erase old labels,new labels were inserted in the center of the web node.The optical packets could transmit long distance in the web.This scheme was proposed and demonstrated by simulation and theoretically prove. |
