超长距离无失真光纤技术 据报道,法国的R&D实验室正在试验一种特殊的光学技术,力争使几千km的光纤传输没有失真。法国专门从事计算机、电子设备、信号处理和图像技术的波根实验室正在利用光的孤波子和短脉冲,可在光纤内实现无失真传输。这一技术可解决色散和非线性效应问题,无需沿光缆设置多个再生装置,只需每100km左右设置一个放大器。
Ultra-long-distance fiber-optic technology without distortion It is reported that France’s R & D laboratories are experimenting with a special optical technology, and strive to thousands of km optical fiber transmission without distortion. The French roots and roots of computer science, electronics, signal processing and imaging technology are taking advantage of solitary and short pulses of light to achieve distortion-free transmission within the fiber. This technology can solve the problem of dispersion and non-linear effects, no need to set up multiple regenerative devices along the cable, just set an amplifier every 100km or so.
