MANUFACTURING DEVICE AND METHOD FOR OPTICAL FIBER PREFORM

WIPO Patent Application WO/2018/098810

A1

A manufacturing device (100) for an optical fiber preform. The manufacturing device (100) comprises a deposition target rod (14), a first blowtorch (15), and a first central control means (20). The first blowtorch (14) is connected to the first central control means (20). The manufacturing device (100) further comprises a diameter measurement unit (19) connected to the first central control means (20). The diameter measurement unit (19) is used for measuring the core diameter of a core rod (401) at preset intervals and feeds back the core diameter to the first central control means (20). The first central control means (20) presets a core diameter target, and sets a measured core diameter as a detection core diameter. When there is a deviation between the detection core diameter and the core diameter target, the first central control means (20) controls and regulates the flow rate of SiCl4 of the first blowtorch (15).
