• FOT6481 Mini Fusion Splicer

FOT6481 Mini Fusion Splicer

FOT6481 implements industrial-grade CPU+FPGA structure of high-performance, completely fresh HD optical fiber microscope, imported high-speed motor and aluminum-magnesium alloy materials extensively. Compared with AV6471, our star product, FOT6481 lowers the size by 38%,the weight by 52%, the power consumption by 57%, but improves the speed by 60%, the environment adaptability by 80% and the reliability (MTBF) by 200%. You can get unprecedented fusion splicing experience.

Intelligent heat shrinkage

A detection unit is embedded in the heater. The heating function will only be enabled when the

thermal shrinkage tube is put in the heater, to avoid misoperation.
