Optical fiber and fabrication process and apparatus of same

摘要

Disclosed herein are a fabrication process of optical fiber, a fabrication machine of optical fiber and optical fiber fabricated thereby. In the fabrication machine, for smoothly supplying sea part fluid into sea parts between adjacent wings, a plurality of cylinders are connected to the bottom of a spinning head. In accordance with the present invention, the above fluid guided by the cylinders is supplied to the space between the adjacent wings with certainty so that the wings are never fused to spin the optical fiber having the predetermined optical characteristics. <IMAGE> <IMAGE>
