Core diameters are 25um, 50um, 100um, 150um, 200um and so on. They are widely used in cutting and welding equipment.
Research, Development, Production and Technical Service of optical fiber cable
In the process of making optical fibers, we should pay attention to
（1）Fiber optic raw materials must be of high purity
（2） Impurity contamination must be prevented and air bubbles must be mixed into optical fibers.
（3）The distribution of refractive index should be correctly controlled.
（4）Correct control of light structure size
（5）To minimize the damage of the optical fiber surface and improve the mechanical strength of the optical fiber.
