Abstract

Procédé et dispositif pour réaliser une ébauche de fibre optique. Ce procédé consiste à plonger une extrémité d'un tube 1 de verre dans un bain 2 en fusion d'un autre verre et à aspirer cet autre verre à l'intérieur du tube 1. Application aux télécommunications optiques.Method and device for producing an optical fiber blank. This method consists in immersing one end of a glass tube 1 in a molten bath 2 of another glass and in sucking this other glass inside the tube 1. Application to optical telecommunications.
