摘要
针对三阶色散对零色散波长附近光脉冲偏振复用技术的破坏作用,提出了使用色散平坦光纤来抑制三阶色散的影响.然而用色散平坦光纤只能在脉冲短距离传输时有效,故提出用正负三阶色散交替的光纤补偿三阶色散对光脉冲偏振复用技术的影响.研究发现该补偿方案能有效地抵消线路的总三阶色散,实现了偏振脉冲长距离稳定传输.
Abstract
Dispersion-flatten fibers are used to suppress the third-order dispersion to some extent based on the effect of third-order dispersion on pulse transmission by polarization multiplexing technique with zero dispersion wavelength. However dispersion-flatten fibers are only useful in short distance transmission. A new method is proposed to compensate the effects of the third-order dispersion by means of the cascade of many short fibers with alternate positive and negative values of the third-order dispersion. The method is proved practicable in long distance transmission by numerical simulation.
