The Fiber optic fusion splicer has four motors, high splice precision, small size, light weight, high reliability, dust/water/shock resistant, touch screen, can replace fujikura fusion splicer 70S. The fiber splice machine is a compact splicer that is primarily used to fuse and protect common communications strands. The splicer’s extensive functionality and extremely low splice loss make it adaptable to fiber splicing in a variety of settings. It has a light weight, small size, higher environmental adaptation, high dependability, dust/wate/shock resistant properties. To suit the needs of a wide range of clients, a variety of fusing and heating modes are provided. The high-precision ceramic V-groove, which is easy to clean and maintain, makes fiber loading more convenient and accurate. Dual-directional fusion is possible with the fiber splicer. The touch screen monitor provides newly designed graphical interfaces that are simple to use. The large-capacity modular pluggable lithium-ion battery ensures long-term field operations. The auto environment adjustment mechanism dramatically increases the splicer’s adaptability to hostile settings, allowing for low-loss splice consistency in a variety of conditions.
