  fiber dispersion
The results confirm in part the analytic expressions for the bulk moduli of such composites previously derived by the authors, but also emphasize the importance of fiber dispersion even at dilute concentrations.
      
Despite the variation of dispersion with wavelength due to the fiber dispersion slope, the transmission in several different channels can be optimized simultaneously using the same optimal launch point.
      
For the case of two-step dispersion maps with distributed Raman amplification to compensate for the fiber loss, we find special schemes that have optimal (chirp-free) launch point locations that are independent of the fiber dispersion.
      
Moreover, the analysis indicates that fiber nonlinearity (which limits the minimum channel spacing) affects the traffic performance more severely compared to fiber dispersion (limits code cardinality).
      
The optical channel is modeled putting into account the combined effect of fiber dispersion, laser source non ideal performances (e.g.

The affection of the optical fiber dispersion on OFDL should not be neglected all the time. For OFDL nolcll filter of current performance, due to dispersion. ND is only 30 dB, which is much lower than the limitation of the measurement system (>55dB). The notch filter can also be used for optical fiber dispersion measurcment, which is simpler and more accurate.

光纤色散对OFDL器件功能的影响并不总能忽略。对OFDL陷波器,在现有器件水平下,由于色散ND只能达到30dB左右,远低于测量系统的限制(>55dB)。利用陷波器,也可以测量光纤色散、该方法具有步骤简便、对器件要求低、精度高等优点。

Furthermore, the compressed pulse is pedestal free. Given inputpulse, we found that the highest peak power and the highest comptession ratio correspondto an optimal decrement velocity of the fiber dispersion which relates not only to theinitisl peak power but also tO the initial pulse width of the input pulse.

本文给出了描述皮秒脉冲在色散缓变单模光纤中孤子效应压缩过程的数学模型.通过数值求解,首次对该孤子效应压缩进行了全面的计算和分析.结果表明,与常规光纤相比,采用色散缓变程度合适的光纤压缩皮秒脉冲,不仅能显著地提高压缩后脉冲的峰值功率和脉冲压缩比,而且能有效地消除压缩后脉冲的次峰和脉座.对于确定的脉冲输入,发现,当光纤的色散缓变程度取某一最佳值时,能获得最佳的压缩效果.进一步研究表明,色散的这一最佳变化与输入脉冲的峰值功率和脉冲宽度有关.
