摘要
搭建在线监测平台对康宁SMF-28单模光纤进行在线监测,得到了光损耗与抛磨深度的关系。在抛磨区长度为10mm时,结果发现,随着抛磨深度的加大,光纤的光功率损耗值逐渐加大,并且损耗值随抛磨深度的变化是非线性的。在抛磨深度为55μm,即抛磨至接近纤芯位置时,光纤的光功率损耗值达到最大-27dB。通过对抛磨深度与光损耗关系的研究,说明该系统可以实时测量光纤抛磨时损耗大小,为抛磨光纤传感器的制作提供了理论和实验基础。
The Corning SMF-28 single-mode fiber is monitored by the platform.The relation between the optical loss and the polished depth has obtained.When the length of fiber polished is 10 mm,it finds that with the increase of grinding depth,optical power loss of optical fiber increases gradually.The loss changed with the depth is nonlinear.When the depth of polished fiber is 55μm,the light power loss reaches the maximum value of-27dB.By the study on the relation between the depth of polished fiber and the light power loss,the fiber can be monitored by the real-time measurement system.The system provides a theoretical and experimental basis for the development of the sensor.
