Multi-hop operation is demonstrated with a prototype hybrid optoelectronic router for optical packet switched networks. The router is realized by combining key optical/optoelectronic device/sub-system technologies and complementary metal-oxide-semiconductor electronics. Using the hop count monitored via the time-to-live field in the packet label, the optoelectronic buffer of the router performs buffering with forward error correction selectively for packets degraded due to multiple hopping every N hops. Experimental results for 10-Gb/s optical packets confirm that the scheme can expand the number of hops while keeping the bit error rate low without the need for optical 3R regenerators at each node.
通过用于光分组交换网络的原型混合光电路由器展示了多跳操作。该路由器通过结合关键的光/光电设备/子系统技术和互补金属氧化物半导体电子器件来实现。利用通过分组标签中的生存时间字段监测的跳数，路由器的光电缓冲器对每N跳因多跳而降级的分组有选择地执行带有前向纠错的缓冲。10 Gb/s光分组的实验结果证实，该方案可以在保持误码率低的同时增加跳数，而无需在每个节点使用光3R再生器。
