摘　　要：文章给出了双曲正弦高斯脉冲传输过程展宽因子的表达式,研究了群速度色散对双曲正弦高斯脉冲有无啁啾两种情况在光纤中传输特性的影响。结果表明,当β2C>0时,该脉冲的展宽因子随传输距离的增大而增大;当β2C<0时,在传输过程中该脉冲会产生初期窄化过程,而后随着传输距离的增加单调展宽。The essay derives the expression of the broadening factors. Furthermore, it studies the details about the influences of the group velocity dispersion on non - chirped hyperbolic sine Ganssian pulse and chirped hyperbolic sine Gaussian pulse in the optical fi- ber transmission. The results show that when β2C 〈 0, hyperbolic sine Gaussian pulse will broaden with the increase of transmission distance; and when β2 C 〉 0, the broadening factors of hyperbolic sine Gaussian pulse will increase monotonically with the monotonic increase of transmission distance.
