130mm fiber preform rod is manufactured by the combined production process of VAD mandrel and OVD cladding. The main component is SiO2, which is doped with other components such as F and Ge in a specific area according to the product characteristics. The outer diameter of the finished preform rod is about 130mm. It is used to fabricate single-mode optical fibers meeting ITU-T G.652.B/D and ITU-T G.657.A1/A2/B3 standards.
