摘要
在对后向泵浦光纤喇曼放大器的泵浦实行强度调制的情况下,通过数值仿真研究了泵浦噪声对高速波分复用系统性能的影响。研究结果表明,相对于低频泵浦噪声,高频泵浦噪声对系统性能的影响更大一些,并且泵浦的损耗和波动可以使信道间隔大的系统性能进一步恶化。
Under the condition that the pump of the counter-pumped fiber Raman amplifiers is intensity-modulated, the effects of pump noise on the performances of high speed WDM systems are investigated through numerical simulation. The results show that the effect of high frequency pump noise is greater than the low frequency ones, moreover, the consumption and fluctuation of pump powers will make the performance of the system with larger channel spacing degrade further.
