| titleOfInvention | Rod type polymer preform having radially-varying properties, process for the preparation thereof and apparatus therefor |
| abstract | The present invention, the step of adding the base material raw material to the tubular reactor, and heating the reactor while rotating the reactor to repeat the step of at least two times, and at this time, to change the type and components of the raw material in each step The present invention relates to a method for producing a rod-shaped polymer base material, the apparatus used in the method, and a rod-shaped polymer base material manufactured by the method, wherein the rod-shaped polymer base material is changed radially from a cross-sectional center in accordance with a specific change rate profile. According to the present invention, modal dispersion is greatly reduced, and a base material for manufacturing an optical fiber with less impurities can be produced. |
