dispersion-flattened fiber meaning in English

色散型平坦光纤

The general nonlinear propagation equations of four - lightwaves in birefringent fibers are deduced . the characteristics of polarization mode dispersion in 4 + 10gb / sdwdm system in dispersion - flattened fibers is studied . our results show that pmd exerts a detrimental influence on 4 x logb / sdwdm system in limiting transmission rate and the channel numbers
本论文研究波分复用( wdm )系统中偏振模色散的影响，主要工作包括下面两个部分：一、导出了四波长光波在双折射光纤中传输所满足的一般非线性耦合方程；在此基础上，研究色散平坦光纤中4 10gb sdwdm系统的偏振模色散特性，并且进一步研究了偏振模色散对不同信道间隔的4 10gb sdwdm系统的影响。
It is found that flat and wideband sc ca n ' t be obtained in common dispersion - shifted fiber , and dispersion - flattened fiber with small normal gvd is most suitable for flat and wideband sc generation ( 2 ) sc generated in dispersion - flattened / decreasing fiber is studied profoundly
结果表明，利用自相位调制效应在常规色散位移光纤一般不能产生平坦、宽带的sc谱。具有较小正常色散的色散平坦光纤有利于平坦、宽带sc谱的形成。 ( 2 )研究了色散平坦渐减光纤中sc谱的产生。
