Abstract

The invention discloses a process for modifying an optical fiber preform, comprising the steps of 1) using a quartz rod cutter to cut a rod preform to obtain a primary quartz rod; 2) secondarily processing the primary quartz rod in a secondary former to obtain a secondary quartz rod; 3) embedding a conductive material in the secondary quartz rod, and sealing with a sealing machine to obtain the optical fiber preform. Special cutting equipment is used herein, zero offset from the axis can be ensured during cutting of a quartz rod, a variable-frequency speed-adjusting motor is arranged in a motor box, speed adjusting is facilitated, and resource and energy can be saved. Special secondary forming equipment is provided, and manual and electric feeding can be achieved; special sealing equipment is also used, non-uniform local distribution of film is avoided, and the preform is more attractive.

Description

technical field [0001] The invention relates to the manufacture of optical fiber preform rods, in particular to a transformation process of optical fiber preform rods, and belongs to the technical field of mechanical processing. Background technique [0002] Optical fiber preform is the core raw material for manufacturing quartz series optical fibers, and it is a special prefabricated rod of glass used for drawing optical fibers. When people manufacture an optical fiber, they first need to make an optical fiber preform, and the internal structure of the optical fiber is formed in the preform, so the manufacture of the preform is the most important part of the optical fiber process. There are many ways to make optical rods, such as chemical vapor deposition, axial vapor deposition, external chemical vapor deposition, plasma activated chemical vapor deposition, etc. When producing the core rod, not only the core but also part of the cladding must be manufactured, this is to...
