Title (EN) METHOD OF DIFFERENTIAL MODE DELAY MEASUREMENT ACCOUNTING FOR CHROMATIC DISPERSION
(FR) PROCÉDÉ DE MESURE DE RETARD EN MODE DIFFÉRENTIEL PRENANT EN COMPTE LA DISPERSION CHROMATIQUE
Abstract:
(EN) A method of characterizing a multimode optical fiber results in a measure of estimated modal bandwidth (EMB) that is independent of the bandwidth of the light used in the characterization. The method includes propagating pulses of light along the multimode optical fiber at prescribed radial positions relative to an optical axis of the multimode optical fiber and detecting output pulses from the multimode optical fiber corresponding to the pulses of light propagated along the multimode optical fiber at the prescribed radial positions relative to the optical axis of the multimode optical fiber. An estimated modal bandwidth of the multimode optical fiber is calculated in a manner that accounts for chromatic dispersion of the multimode optical fiber.
(FR) L'invention concerne un procédé de caractérisation d'une fibre optique multimodale entraînant une mesure de bande passante modale estimée (EMB) indépendante de la bande passante de la lumière utilisée dans la caractérisation. Le procédé comprend la propagation d'impulsions de lumière le long de la fibre optique multimodale à des positions radiales prescrites par rapport à un axe optique de la fibre optique multimodale et la détection d'impulsions de sortie en provenance de la fibre optique multimodale correspondant aux impulsions de lumière propagée le long de la fibre optique multimodale aux positions radiales prescrites par rapport à l'axe optique de la fibre optique multimodale. Une bande passante modale estimée de la fibre optique multimodale est calculée d'une manière qui tient compte de la dispersion chromatique de la fibre optique multimodale.
