摘　　要：为减少光纤参数波动超标,提升有效拉丝长度,基于外部气相沉积(OVD)法制棒技术研究了芯棒和尾柄的对接工艺及其与接口附近光纤参数的关系,阐述了利用自动数控车床进行芯棒和尾柄对接的工艺方法,理论分析了对接工艺对光纤性能影响的原理,并将不同对接工艺的芯棒进行拉丝对比实验。实验结果表明:使用该对接工艺的芯棒跳动值一次符合率可从90%提升至98%以上,确定了利于减小光纤模场直径波动的挤压程度DD0为1.2,且氢氧比2∶1.1是在不产生接口气泡前提下使光纤水峰性能最优的对接参数。In order to reduce the over standard fluctuation of optical fiber parameters and improve the effective drawing length,based on OVD manufacturing technology,the core rod and handle connection process and its relationship with optical fiber parameters near the interface are studied.The connection process of core rod and handle using automatic computer numerical control lathe is described.The influence of connection process on optical fiber performance is analyzed theoretically,and comparative experiments were carried out by drawing the core rods with different connection process.The experimental results show that the one-time coincidence rate of the core rod runout value can be increased from 90%to more than 98%.It is established that the extruasion dgree DD0 which is beneficial to reduce the fluctuation of mode field diameter is 1.2,and the hydrogen oxygen ratio 2∶1.1 is the optimal connection parameter for the optical fiber water peak performance without interface bubbles.
