An optical fiber connector with an adjusting mechanism using double eccentric tubes is reported. Tolerable impairment values of possible factors affecting connection loss are evaluated. The main factors of the connection loss are mutual core displacement and fiber axis tilt. By using a double eccentric adjusting mechanism, a 0.57-dB average connecting loss between step index multimode fibers is obtained without matching material. The connection loss can be attributed quantitatively to several impairment factors. Using a transparent thin film in the connecting section, the reflection can be reduced as low as about -25 dB, and the average connecting loss was improved to about 0.20 dB.
报道了一种采用双偏心管调节机构的光纤连接器。评估了影响连接损耗的可能因素的可容忍损伤值。连接损耗的主要因素是芯间位移和光纤轴倾斜。通过使用双偏心调节机构，在不匹配材料的情况下，阶跃折射率多模光纤之间的平均连接损耗达到了0.57dB。连接损耗可以定量地归因于几个损伤因素。在连接部分使用透明薄膜，反射可降低至约-25dB，平均连接损耗提高到约0.20dB。
