沿途不用中继器实现横跨大西洋的光纤传输系统也许是遥远将来的事情,但是光纤的先驱者Charles Kao在今年的光纤通信专题讨论会上指出,在21世纪的某个时期,也许能实现这种长距离的信号传输。将来要实现的无中继传输的距离,实际上大约是目前的30倍。传输这种长距离无中继信号的先 It may be a distant future for transatlantic optical fiber transmission systems without repeaters along the way, but optical fiber pioneer Charles Kao noted at this year’s Fiber Optic Symposium that at some point in the 21st century this may be possible Long-distance signal transmission. In the future to achieve the distance without relay, in fact, is about 30 times the current. Transmission of this long-distance relayless signal first
