Replace traditional gas-heating method by electrical heating method in optical devices manufacture,a new type of electrical FBT(Fused Biconical Taper)heater is developed.Based on this,a new type of FBT machine with electrical heater was developed which can precisely control temperature within the tolerance of±2℃,much better than that of gas-burning method.Lastly,fiber couplers was fabricated on this new machine and its disperse performances was compared with those made by gas-burning machine.The result shows that the new electrical FBT machine can greatly improve the conformity of the fiber devices.
