摘　　要：对非线性前色散补偿系统中的完全补偿、过补偿和欠补偿进行了数值模拟。数值结论表明：采用非线性前补偿不论是完全补偿、过补偿还是欠补偿，当入纤平均功率为1mW至15mW时20Gbit／s、最大半宽度为20ps的RZ脉冲经过100km的标准单模光纤后均能满足误码率小于10－9的要求。当入纤功率较大时，采用完全补偿经过一个放大距离后Q值最大，而且能够传输的放大周期也最多。Full compensation, overcompensation and undercompensation of employing the nonlinear dispersion compensation technology of standard single mode fiber following dispersion compensation fiber are numerically analogized. The results show that it is possible for the return-zero optical pulse with bit rate=20Gbit/s, The pulse width =20ps and the input mean power=1-15mW to transmit over 100km along standard optical fiber when the compensation configuration is full compensation, overcompensation and undercompensation,respectively. When input mean power is large,Q value of the optical pulse by employing total compensation is large after the optical pulse transmits over a amplifer spacing,and the maximum transmission distance is long.
