摘　　要：利用长度为10 km的长距离传输七芯光纤模拟实际干路,对多芯光纤熔接技术进行了实验研究,并通过传输性能测试分析进行了熔接参数优化。实验结果表明:多芯光纤的熔接质量直接影响光纤传输损耗和串扰;熔接质量受光纤端面的处理质量、光纤重叠量、放电时间、电极间距等参数的综合影响。实验中通过程序控制多个熔接参数关联性优化,实现了典型值小于0.35 dB的低损耗七芯光纤熔接,且串扰小于-41 dB,可以更好地满足工程干路铺设的应用要求。The actual trunk multi-core fiber(MCF)splicing is studied by a 10-kilometer of 7-core fiber for long distance transmission and the splicing parameters are optimized by transmission performance test.The results show that the quality of MCF splicing affects both transmission loss and crosstalk.The splicing quality is influenced by end-face treatment,discharge intensity,discharge time,electrode spacing and other parameters.By aligning the fusion splicer controlled by the axis algorithm and optimization of the relevant splicing parameter,the low-loss 7-core fiber splicing is achieved.The typical value of splicing point loss can be less than 0.35dB and crosstalk can be less than-41dB,which can better meet the requirements of application for engineering wiring.
