模拟了皮秒高斯光脉冲在理想的二阶和三阶色散都作了补偿的光纤链中的传输。结果表明 ,与二阶色散补偿能消除脉冲展宽一样 ,三阶色散补偿不仅能防止脉冲展宽 ,而且也能有效地消除脉冲边沿部的振荡结构和脉冲峰的时移。文中画出了 10 0Gb/s码率的 6 4位高斯光脉冲序列在色散补偿光纤链中传输 2 0 0 0km后的眼图 ,由眼图的清晰程度可看出这种补偿系统对改善短脉冲传输的有效性。
Simulation of picosecond Gaussian optical pulses in the ideal second and third order dispersion have been compensated fiber optic chain transmission. The results show that the third-order dispersion compensation can not only prevent the pulse broadening, but also effectively eliminate the oscillation of the pulse edge and the time-shift of the pulse peak, as the second-order dispersion compensation can eliminate the pulse broadening. In this paper, an eye diagram of a Gaussian optical pulse sequence of 60 Gbits / s at a rate of 100 Gb / s is transmitted in a dispersion-compensated fiber chain of 2000 km. From the clarity of the eye diagram, it can be seen that this compensation system is effective in improving short Effectiveness of pulse transmission.
