Lateral displacement has a great influence on optical communication. We proposed the directional tapered fiber connector to improve the coupling efficiency. To verify its performance, we produce the sample with the flame-brush technique. In the next step, two experiments in the vibration environment are done. The first experiment shows the tapered structure could improve the optical power coupling efficiency. In addition, in this experiment, we discover only the amplitude has an obvious impact on the power coupling efficiency. The second experiment shows the bit error rate of the common receiver is higher than that of the new receiver. It indicates the new receiver performs better also. At the same time, the second experiment shows both the amplitude and frequency have obvious influence on the bit error rate result. This is different from the first experiment. The reason is owing to that the vibration frequency will change the mode of laser transmission. However, the transmission mode has an obvious impact on the bit error rate, but has little influence on the optical power coupling efficiency.

横向位移对光通信有很大的影响。我们提出了定向锥形光纤连接器以提高耦合效率。为了验证其性能，我们使用火焰刷技术制作了样品。在下一步中，在振动环境中进行了两个实验。第一个实验表明锥形结构可以提高光功率耦合效率。另外，在本实验中，我们发现只有振幅对功率耦合效率有明显影响。第二个实验表明普通接收机的误码率高于新接收机。这表明新接收器的性能也更好。同时，第二个实验表明幅度和频率对误码率结果都有明显的影响。这与第一个实验不同。原因是由于振动频率会改变激光传输的模式。但传输方式对误码率影响明显，而对光功率耦合效率影响不大。
