摘要
提出了一种利用光纤色散特性产生超宽带脉冲信号的光学方法.对12.5G b/s伪随机序列的传输特性进行了仿真,结果表明:高斯脉冲通过光纤传输系统后,时域上获得的脉冲信号接近于FCC的超宽带脉冲波形模板,频域上获得的信号频谱接近于FCC的频谱规范.
A method of utilizing the fiber dispersion to generate ultra-wide-band pulse signals is simulated.Transmission performance simulation for 12.5Gb/s psudo-random sequence also shows that Gaussian pulse signal after transported in fiber is similar to UWB wave pattern mask of FCC in time domain and frequency spectrum specification of FCC in frequency domain.
