Research on Fusion Splicing Technology of 7-Core Fiber

The actual trunk multi-core fiber (MCF) splicing is studied by a 7-core fiber for long-distance transmission. 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 fibers controlled by the axis algorithm and optimization of the fusion splicing parameter, the typical value of splicing point loss can be less than 0.3 dB, which can better meet the requirements of application for engineering wiring.
