日本电信电话公司最近利用现有的普通光缆通信线路成功地进行了超高速远距离光孤立子通信试验。该试验达到每秒可将2万兆位数据的信息传递1000公里的成果。 光孤立子通信是利用波在一定的速度下不改变形态就可传送信息的特殊性进行信息传递的技术。从理论上讲,现有的光缆通信网络每隔数公里就有接口,具有改变波形态的性质,不适合光孤立子通信,如果要进行光孤立子通信需要重新铺设特殊光缆。 但是,日本电信电话公司是在水户和前桥两地之间的 Nippon Telegraph and Telephone Corporation recently successfully conducted a very high speed long-distance optical soliton communication test using the existing ordinary optical cable communication line. The experiment reached the result of delivering 1,000,000 kilometers of information per 20,000 megabits per second. Optical soliton communication is the use of wave at a certain speed without changing the form of information can be sent to the particularity of information transmission technology. In theory, existing optical fiber communication networks have interfaces every few kilometers, which has the property of changing the waveform morphology and is not suitable for optical soliton communication. If optical soliton communication is to be carried out, special optical cables need to be re-laid. However, Nippon Telegraph and Telephone Corporation is between Mito and Maebashi
