一种新型波动现象——孤立波的研究利用,最近取得重要进展。美国贝尔实验室研究人员,在使波形保持不变,也无需加装电子放大器的条件下,成功地将激光脉冲信号传递了5920公里。根据这一最新科研成果,美国光谱物理公司已制成能产生万亿分之四秒的孤立波脉冲信号的器件,在不久的将来可制成能产生十万亿分之一秒的脉冲信号的器件。如果将这些成果用于现有光通信线路,每秒将
A new type of wave phenomenon, the study and application of solitary waves, has recently made important progress. Researchers at Bell Laboratories in the United States succeeded in transmitting 5,920 kilometers of laser pulse signals while keeping the waveform unchanged and without having to install an electronic amplifier. According to the latest scientific research, the United States spectral physics company has made a device capable of generating isolated wave pulse signals of four trillionths of nanoseconds, and in the near future it can be made into a pulse signal capable of generating ten billionths of a second Device. If these results for the existing optical communications lines, will be per second
