  • Product Overview:

    6481 Series 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.

    Small and light

    Small size and light weight, the splicer is easy to carry and can be lift by one hand.

                                                                                  Lift by one hand

    Water-resistant, dust-resistant, shock-resistant, greater environment adaptability

    Meet IP52 requirements.

    All-in-one fixer

    The all-in-one fixture meet fusion demands of multiple optical fibers, jumpers and rubber-insulted wires with a cladding diameter of 80~150μm.



    Graphical interfaces and touch screen 

    AV6481 uses entirely new GUI and touch screen in design. Operators can set up the splicer and get to know relevant information of it simply and directly by graphical interfaces. 


    Intelligent heat shrink

    A detection unit is embedded in the heater. The heating function will only be enabled when the protection sleeve is put in the heater, to avoid mishandling.

    Ceramic V-groove and ceramic presser foot

    Ceramic V-groove with high precision brings you convenient and accurate placement of optical fibers and makes cleanup easy.


                                High-precision ceramic V-groove and presser foot 


    Carrying case

    The carrying case is novel in design and light in weight, has built-in compact working bench. Open or close the cover can turn it to a working bench.



    Typical Applications

    6481 Series Optical Fiber Fusion Splicer is compact equipment deploying the design of ergonomics, which delivers convenient operation and handy carrying case. Event very short fibers can be spliced easily. It’s capable of construction and maintenance of optical fiber line projects (including trunk), emergency repair, production and test of optical fiber devices and research and study in institutes.
