Measurement of Chromatic Dispersion of Single Mode Fibers by Mask Method 掩模法测量单模光纤的色散
In optical telecommunication systems, one of the many difficulties encountered is the chromatic dispersion of light signals propagating over long distances in optical media such as optical fibers. 在光通信系统中,众多难题之一是光信号在长距离光纤传输后会产生色散现象。
Based on this theory modal, a new spectral-domain intermodal chromatic dispersion difference measurement method have been proposed. The results obtained by this method can provide usefull data for numerical dispersion compensation in polarization mode coupling measurement and polarization-maintaining fibers sensors based on intermodal interference. 提出了一种白光频域干涉保偏光纤模间色度色散差的测量方法,能为保偏光纤偏振耦合测量和基于保偏光纤模间干涉原理的光纤传感器提供数值色散补偿的准确数据。
