利用检测单模双折射光纤弯曲传输损耗装置测绘了光纤的弯曲损耗图及光纤弯曲传输模式图。

Using the instrument for the transmission loss of single mode of winding birefringence optical fiber, the spectrogram of loss and the graph of mode density are obtained.

通过计算发现，随着中间电极角度和地电极角度增加，有效折射率、特征阻抗同时减小，导体损耗系数也随之减小。

The calculation results have shown that when the angles of the center electrode and the grounds decrease, the effective index, the characteristic impedance, and the conductor loss all decrease.

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。

After the simulation, the relationship of fundamental mode loss with the core index, wavelength and the diameter of cladding air holes is given.
