| 摘 要： | 本文数值模拟了强度调制光信号在级联光纤放大器常规ＳＭＦ通信系统中的传输，在模拟中主要考虑了自相位调制、群带色散和ＡＳＥ噪声。我们使用负色散补偿光纤去补偿群速色散和自相位调制。结果表明如果色散得到很好的补偿，当放大器的间距减少到５０ｋＭ时，无误码２０５０ｋｍ传输是可能的。

| Abstract: | The propagation of intensity-modulated signal in an cascaded optical amplifier conventional simple mode fiber system is numerically analyzed, taking self-phase modulation (SPM), group-velocity dispersion (GVD), amplifier spontaneous emission (ASE) into account. The effect of GVD and SPM are reduced by dispersion compensation fibers (DCF's). The simulation show if dispersion is well-compensated and amplifier spacing is decreased to 50 km, the distance 2 050 km is possible with errorfree. |
