摘要
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。
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.
