FBT Coupler production machine for PM coupler, combiner, multimode splitter production

COUPLER KWFBT-8000 fiber fused biconical coupler machine is a kind of coupler manufacturing equipment with high repeatability, good
stability and low failure rate, which specially designed for coupler manufacturers. Since putted into the market, it received
abundant popularity, it equipped with the Japanese screw module and German control system and high precision optical fiber
fixture. Besides, it has the function of data storage, productivity statistics, packaging temperature monitoring and so on.
Furthermore, it can control the coupler machine by embedded BOX machine, meanwhile, it allows display devices, keyboard and mouse
directly connecting to mainframe machine and using, which economized more room for operation.
