| 摘 要： | 在分布放大传输系统中建立了随机色散模型,利用自伴算符法研究了随机色散的影响。结果表明:随机色散与放大的自发辐射噪音联合作用增大了传输系统的时间抖动,其中与传输距离有关的随机色散具有长距离效应,而与孤子频移有关的随机色散具有短距离效应。

| Abstract: | The model of stochastic dispersion variation is built in soliton distributed amplification transmission system,the influence of stochastic dispersion variation on transmission system is studied by self companying operator method The results show:the combined role of stochastic dispersion variation and amplified spontaneous emission noise increases the time jitters in arrival,the influence caused by the stochastic dispersion varying with propagation distance has long distance effect,and the influence of stochastic dispersion variation caused by frequency shift of soliton has short distance effect |

| Keywords: | Soliton transmission Stochastic dispersion Self companying operator method Time jitters in arrival |
