| 摘 要： | 光纤传输质量受光纤损耗的影响，对单模光纤传输波长1310nm和1550nm弯曲损耗进行测试，结果表明弯曲损耗呈震荡变化，随着弯曲半径的增加损耗减小、振幅减小，随着波长的增加损耗增加、振幅增大，并利用光纤的耦合模理论对单模光纤弯曲损耗震荡进行解释，对实际应用有一定的参考价值。

| Abstract: | The loss of optic fiber influences the transmission quality of communication,tested the bending loss of the single model optical fiber by using the operating wavelength 1310nm and 1550nm,the result shows that the bending loss assumes the shake change,and along with the bending radius increase,lose reduces,amplititude reduces,but along with wave length increase,lose increases,amplitude increase.explained the single-mode fiber bending shock loss by using the theory of fiber-coupled mode.It has a certain reference value for the practical application. |

| Keywords: | bending loss absorption loss single-mode optical fiber mode-disturbing device |
