| 摘 要： | 3R(re-amplification,re-shaping,re-timing)再生是高速率光纤通信系统的一个关键技术。为科学评价3R系统的再生能力,对基于色散位移光纤(DSF)中的四波混频(FWM)效应的全光3R系统的性能进行了测试,得到了输入-输出信号Q值的特性曲线,由此可以得到3R再生系统的再生范围(可再生输入信号的最小输入Q值和最大输出Q值)、最大再生能力等信息,从而达到合理地在线路中设置3R再生系统。结果表明,对于此全光3R再生系统,对输入Q值在2.6～5.8的恶化信号具有再生能力,并且在输入信噪比(SNR)为3.2时可以得到最大的SNR改善为1.1。

| Abstract: | The 3R (re-amplification,re-shaping,re-timing) regeneration is one of t he key technologies for the high-speed optical communication systems.How to set the 3R regeneratio n system in the transmission line more reasonably and more efficiently might need to be solved i n the high-speed system.There is a regenerative capacity for any regeneration system,and the rege nerative capacity varies with input signals.So for the signal with a spec ific deterioration,testing the regenration effect cannot describe the regeneration capacity of the 3R syste m.Changing the deterioraton of the input signal,we can get the regenerative capacity of the 3R regeneration system,which is decided by the minimum input Q value and the maximum input Q value,an d the maximum regenerative capacity.In this paper,the regenerative curve for a 40Gbit/s 3R regeneration system is shown,which is based on four-wave mix ing in a dispersion shifted fiber (DSF). This all-optical 3R regeneration system can regenerate the degraded signals wit h a Q value ranging from 2.6to 5.8.The maximum improvem ent of the signal to noise ratio (SNR) is 1.1when the i nput SNR is 3.2. |
