Abstract: With the introduction of 5G, cloud computing, data center and other concepts, the optical fiber technology not only puts forward the demand of quantity, but also requires the development of optical fiber technology to meet the needs of new applications. Fiber equipment technology is the cornerstone of optical fiber technology, in which plasma equipment technology can realize the development of a variety of large-capacity new optical fiber technology, with a wide range of application prospects and significant research value. Through the relevant simulation, a device based on PCVD fiber precast rod microwave system is designed. The fiber precast rod is successfully manufactured by the device, which proves that the design of microwave system device has a good feasibility. It has certain economic value and development prospects.

Key words: fiber precast rods, microwave discharge systems, microwave simulation, fiber testing
