After the simulation, the relationship of fundamental mode loss with the core index, wavelength and the diameter of cladding air holes is given.
通过模拟，给出基模损耗同芯折射率、光波长和包层空气孔直径之间的一般规律。
The method is compared with the simple analysis for loss characteristics of cladding modes propagating through the fiber and the measured results are in good agreement with theoretical curves.
该方法与以往所做的对沿光纤传播的包层模式功率的损失特性的简单分析对比，测量结果与理论曲线十分相符。
The index of the core is a little smaller than that of the cladding base material, so the fundamental mode loss of short wavelength increases rapidly and leads to the mode cutoff.
这种光纤的纤芯折射率比包层基质折射率小，所以短波长时基模损耗迅速增大，使得光传输截止。
