As the fiber fusion splicer manufacturer, BD-FS-81 fiber optic fusion splicer is small size optical fiber fusion splicer, mainly used for fusion splices and protection of common communications fibers. The fiber optical fusion splicer with rich functionality and ultra-low splice loss make the fusion splicer adaptive to fiber splicing in various environments. The fiber optic fusion splicer is featured with small size, light weight, high reliability, greater environmental adaptability, dust-resistant, water-resistant and shock-resistant. Multiple fusion modes and heating modes are available to meet diversified customers’ demands. Fiber loading becomes more convenient and accurate thanks to the ceramic V-groove of high precision, which is easy for clean and maintenance. The fusion fiber splicer is capable of dual-directional fusion. The monitor is a touch screen delivers fresh designed graphical interfaces, the fiber optic fusion splicer are simple for operation. The modular pl able lithium-ion battery of large-capacity ensures long-time field operations. The auto environment compensation system greatly improves adaptability of the fiber splicer to hostile environments, so that low-loss fusion splice can be remained consistent in various environments.
