Introduction
Mini Fused Optical Couplerare manufactured by Fused Biconical Taper (FBT) technique. The principle is that two fibers are fused by oxyhydrogen flame and pulled to subulate by using the special pulling device. Then the light inputed one length of fiber is splited to the other fiber, so is the light power. The ratio (Coupling Ratio) of the power distribution can be set as required.The entire process of the pulling process is to be monitored by computer,and can stop according to the setting spetral of the device.
