IEC 60793-1-21-ed.1.0

Annotation of standard text IEC 60793-1-21-ed.1.0 :

Gives four methods for measuring the coating geometry of optical fibres. The following parameters are measured: coating diameter, coating non-circularity, coating-cladding concentricity error. The methods are conducted off-line during inspection. They are not suitable for on-line, in-process measurements. Presente quatre methodes pour mesurer la geometrie du revetement des fibres optiques. Les parametres suivants sont mesures: diametre du revetement, non-circularite du revetement, erreur de concentricite du revetement-gaine. Chaque methode est effectuee a part pendant le controle. Aucune delle nest adaptee a des mesures directes, en cours de processus.
