结果表明，在放大器间距小于非线性演化长度尺度的条件下，光脉冲在集总放大系统中的传输动力学可用无损耗非线性薛定谔方程描述。本说明中涉及的误差被量化，并且在放大器间距的平方的数量级上。作者还考虑了另一种方法的脉冲预加重已被提出，他们展示了它是如何与平均孤子方法。<<ETX>>
It is shown that the dynamics of optical pulse propagation in lumped amplified systems is described by the lossless nonlinear Schrodinger equation under the condition that the amplifier spacing is short compared to the nonlinear evolution length scale. The errors involved in this description are quantified and are on the order of the square of the amplifier spacing. The authors also consider an alternative method of pulse preemphasis which has been proposed, and they show how it relates to the average soliton method presented.<<ETX>>
