Problems solved by technology
However, no matter which method is used to manufacture the optical fiber preform, in the manufacturing process, due to the influence of some factors, the product yield is not high, such as the ambient temperature of the core rod due to the fluctuation of the air flow during the exhaust. Fluctuations, resulting in uneven distribution of dopants in the core layer, resulting in poor axial profile consistency

Abstract
The invention relates to manufacturing equipment of optical fiber precast rod. The manufacturing equipment comprises a deposition target rod, a deposition blowtorch and a central control device; a blowtorch port of the deposition blowtorch is formed towards the deposition target rod; the deposition blowtorch is connected with the central control device. The manufacturing equipment further comprises a distance measurement unit connected with the central control device, the distance measurement unit is used for monitoring the rod diameter of the precast rod and feeding back the monitored rod diameter of the precast rod to the central control device; the central control device is used for adjusting the SiCl4 flow rate of the deposition blowtorch. The invention further provides a manufacturingmethod and a manufacturing system of the optical fiber precast rod. The manufacturing equipment, the manufacturing method and the manufacturing system of the optical fiber precast rod, provided by the invention, have the benefits that the SiCl4 flow rate of the deposition blowtorch is adjusted according to the rod diameter monitored by the distance measurement unit; the correction on the diameterin the deposition process is realized, so that the rod diameter of the precast rod has good consistency, and the performance and the manufacturing yield of the precast rod are further improved.
Description
technical field [0001] The invention relates to the technical field of manufacturing optical fiber preforms, in particular to a manufacturing system for optical fiber preforms. Background technique [0002] Optical fiber preform manufacturing is divided into core rod manufacturing and outer cladding manufacturing, that is, the core rod (including the core layer and optical cladding) is manufactured first, and then the cladding is deposited on the outside of the core rod to obtain an optical fiber preform rod. The manufacturing methods of optical fiber preform core mainly include axial vapor deposition (VAD), modified chemical vapor deposition (MCVD), plasma chemical vapor deposition (PCVD) and out-of-tube vapor deposition (OVD). Fabrication is dominated by direct OVD synthesis and quartz sleeve assembly. However, no matter which method is used to manufacture the optical fiber preform, in the manufacturing process, due to the influence of some factors, the product yield is n...
