(Main)Optical fibres - Part 1-41: Measurement methods and test procedures - Bandwidth
Optical fibres - Part 1-41: Measurement methods and test procedures - Bandwidth
Describes two methods for determining and measuring the modal bandwidth of multi-mode optical fibres (see EN 60793-2-10, EN 60793-2-30 and EN 60793-2-40).The baseband frequency response is directly measured in the frequency domain by determining the fibre response to a sinusoidally modulated light source, it can also be measured by observing the broadening of a narrow pulse of light. Method A - Optical time domain measurement method (pulse distortion). Method 2 - Frequency domain measurement method. Each method can be performed using one of two launches: an overfilled launch (OFL) condition or a restricted mode launch (RML) condition.
Lichtwellenleiter - Teil 1-41: Messmethoden und Prüfverfahren - Bandbreite
Fibres optiques - Partie 1-41: Méthodes de mesure et procédures d'essai - Largeur de bande
Deux méthodes pour mesurer la largeur de bande sont présentées: la réponse impulsionnelle, et la réponse fréquentielle. Les deux méthodes s'appliquent à la mesure de la largeur de bande des fibres multimodales de catégorie A1. L'application aux autres catégories de fibres multimodales de classe A est à l'étude. Aucune des méthodes ne s'applique à la mesure de la larguer de bande sur fibres unimodales de type B.
