横向位移对光纤头续接耦合效率有很大影响。提出采用有方向性锥形光纤连接器来提高耦合效率,和传统连接器相比,新的连接器扩大了入射光接收面积,从而提高接收性能。对锥形光纤的全反射特征和功率耦合特征进行了理论分析,理论分析结果表明新的锥形光纤头能有效提高耦合效率。为了进一步验证新连接器的性能,试制了样品,并在微振动环境中开展了误码率实验。实验结果表明,在微振动环境下,新的锥形连接器误码率更低,性能更好。

The transverse displacement significantly affects the coupling efficiency of fiber head.This paper introduces a directional tapered fiber connector designed to enhance coupling efficiency.Compared with the traditional connector,the new connector expands the receiving area of the incident light to improves the receiving performance.Next,the total reflection characteristics and power coupling characteristics of tapered fiber are analyzed theoretically.The theoretical analysis results show that the new tapered fiber head can effectively improve the coupling efficiency.To validate the performance of the new connector,a sample was fabricated and subjected to bit error rate experiments under micro-vibration conditions.The experimental results confirm that the tapered connector exhibits a lower bit error rate and superior performance in micro-vibration environments.
