 Optical Fiber Preform

Potevio Fasten applies the innovated AFHD to fabricate optical fiber preform. It is featured by high efficiency and consistency compared with the preforms fabricated by traditional method. Its main advantages are fine birefringence distribution and geometric parameters from which low-attenuation, low water peak and high-strength fibers can be drawn.
