摘要：

A new soliton transmission method with lumped amplifiers is presented. We call this the preemphasis method. An N = 1 soliton with relatively high amplitudes (1.2 < A < 1.4), which is used as an input soliton, plays an important role in a lumped gain soliton transmission system. The initial soliton pulse width can be preserved after propagation over long distance despite the existence of fiber loss. It is shown that with the lumped gain, the soliton pulse can propagate over more than 9000 km when the repeater spacing is 31 km and fiber loss is 0.22 dB/km. © 1990 IEEE
