Abstract

The invention relates to the technical field of optical fiber preform production, in particular to optical fiber preform manufacturing equipment which comprises a sealing mechanism, a microwave resonant cavity and an air inlet pipe, wherein the sealing mechanism comprises an air inlet end sealing piece and an air outlet end sealing piece arranged at an interval for sealing the two ends of a reaction pipe; the microwave resonant cavity is used for being arranged on the outer side of the reaction tube in a sleeving manner and can do reciprocating motion in the axial direction of the reaction pipe; and the air inlet pipe comprises an air outlet end used for extending into the reaction pipe, the air inlet pipe penetrates through the air inlet end sealing piece, and the air outlet end is configured to synchronously reciprocate with the resonant cavity in the reaction pipe. The problem that in the prior art, due to the fact that the reaction concentrations of reactants in a reaction pipe atall deposition points are inconsistent, an optical wand is not uniform in the axial direction can be solved.

Description

technical field [0001] The invention relates to the technical field of optical fiber preform production, in particular to an optical fiber preform production equipment. Background technique [0002] In recent years, with the large-scale deployment of 4G and the commercial use of 5G, the digitalization process is advancing rapidly, and people's demand for data transmission is also increasing day by day. At the same time, as the most important part of data transmission, communication optical fiber has always been concerned by people. [0003] The PCVD plasma chemical vapor deposition process is currently the most commonly used method for preparing communication optical fibers. This process can deposit thousands of layers, so it is very precise in waveguide structure design, material composition and structure design. It has the characteristics of high-precision refractive index distribution control, high deposition efficiency, and excellent flexibility. The PCVD process can n...
