| 摘 要： | 利用保偏光纤受外界干扰时主轴变化，从而传输光的偏振度发变化，以传输光的偏振度为敏感参数，实时检测介入窃听，给编码保密通信增加了一个保密度，以光行被弯曲的半径来定义窃听检测阈值，典型阈值是8．5mm.

| Abstract: | The polarity of light transmitted in polarization maintaining optical fibers of a confidential telecommunication system is dependent on artificial and environmental interfere to the fiber. The polarity may be taken as sensing parameter to detect in real time the wiretapping to the telecommunication. The threshold of wiretapping detecting is defined by the bend radius of the fiber, the typical value is 8.5 mm. |
