光纤通信网络中的光电交换节点成了现今高速率传输的“瓶颈”地段。美国普林斯顿大学最近的研制成功了一种称之为“全光分组交换法”的路由器，速率高达250Gb／S。经测试表明，这种分组交换的比特误码率优于10－‘。这种路由器的研制成功，解决了当前高速率传输交换系统的难题 Optoelectronic switching nodes in optical fiber communication networks have become “bottleneck” lots of high-speed transmission today. The United States recently developed a successful Princeton University called a "all-optical packet switching method of the router, the rate of up to 250Gb / S. The test shows that this packet exchange bit error rate better than 10- ’. The successful development of this router solves the current high-speed transmission switching system problems
