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。
Aiming at the destructive effect of third-order dispersion on the polarization multiplexing of light pulses near zero-dispersion wavelength, the effect of using third-order dispersion-suppressed fiber to suppress third-order dispersion is proposed. However, the dispersion-flattened fiber can only be effective in the short-pulse transmission. Therefore, it is proposed that the third-order dispersion compensated by the third-order dispersion of positive and negative fibers affect the optical pulse polarization multiplexing. It is found that the compensation scheme can effectively cancel the total third-order dispersion of the line and achieve the long-term stable transmission of the polarized pulse.
