Optical fiber communication systems primarily operate at wavelengths near 1.55 渭m in order to coincide with the minimum loss point of optical fiber and thereby maximizing the transmission distance. But, at this wavelength, there is a significant amount of group velocity dispersion (GVD) that limits...
The influence of the modal dispersion of signal fiber on velocity measurement in VISAR applications; 激光干涉测速中信号光纤的模式色散对速度测量的影响 2. The paper compares the structural parameters and amount of modes between multimode fiber and polymer optical fiber,then analyses that a large amo...
