By gradually translating the peak frequency of guiding filters along its length, we create a fibertransmission line that is substantially opaque to noise while remaining transparent to solitons. This trick allows the use of stronger filters, and hence greater jitter reduction, without incurring the usual penalty of exponentially rising noise from the excess gain required to overcome filterloss.
通过沿其长度逐渐平移导向滤波器的峰值频率，我们创建了一种光纤传输线，它对噪声基本不透明，而对孤子保持透明。这个技巧允许使用更强的滤波器，从而实现更大程度的抖动降低，同时不会因克服滤波器损耗所需的额外增益而产生通常的指数级上升噪声的代价。
