Abstract

On décrit une fibre optique (14) fabriquée par étirage à partir d'une préforme (10) et alimentée dans un four à un débit de distribution supérieure constant. Cette fibre optique (14) est étirée par un tracteur (20) à un débit d'au moins 10 mètres par seconde, et le tracteur (20) peut varier la vitesse d'étirage de la fibre (14) en fonction du diamètre de la fibre mesuré par un dispositif de contrôle du diamètre (15) pendant le processus d'étirage, afin de maintenir un diamètre de la fibre relativement constante. Le fait de maintenir le débit de distribution supérieure de la préforme à un niveau constant même à des débits d'étirage élevés dépassant 20 mètres par seconde n'est pas préjudiciable au processus d'étirage, mais permettrait même de réduire ou d'éliminer les oscillations de la boucle de commande qui peuvent entraîner des variations dans l'ébauche du coeur pendant la formation de la fibre, ce qui donne comme résultat une dispersion en mode polarisé (PMD) réduite et une uniformité améliorée du diamètre mode-champ (MFD).
