By launching a modulated Raman pump along with a soliton, we can reduce the random walk of solitons caused by the amplifier noise. The pump injected at one amplifier is filtered out at the next amplifier position. The group-velocity mismatch plays the role of a sliding frequency under properly chosen parameter space.
通过与孤子一起发射一个调制拉曼泵浦，我们可以减少由放大器噪声引起的孤子随机游走。在一个放大器处注入的泵浦在下一个放大器位置被滤除。在适当选择的参数空间下，群速度失配起到了滑动频率的作用。
