Focus on Fiber Optical(FTTH) Equipment & Tester & Tools Since 2011.

FOT6481A Optical Fiber Fusion Splicer

FOT6481A Optical Fiber Fusion Splicer is small size optical fiber fusions splicer, mainly used for fusion and protection of common communications fibers. The rich functionality and ultra-low splice loss make the splicer adaptive to fiber splicing in various environments. It 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 splicer is capable of dual-directional fusion. The monitor is a touch screen delivers fresh designed graphical interfaces, which are simple for operation. The modular pluggable lithium-ion battery of large-capacity ensures long-time field operations. The auto environment compensation system greatly improves adaptability of the splicer to hostile environments, so that low-loss splice can be remained consistent in various environments.
