Abrégé
(EN)
Systems and methods include causing transmission of one or more shaped Amplified Spontaneous Emission (ASE) signals, from an ASE source (70), on an optical fiber (58, 60); obtaining received spectrum of the one or more shaped ASE signals from an optical receiver (68) connected to the optical fiber (58, 60); and characterizing the optical fiber (58, 60) based in part on one or more of a nonlinear skirt and a center dip depth in the received spectrum of the one or more shaped ASE signals. The one or more shaped ASE signals can be formed by the ASE source (70) communicatively coupled to a Wavelength Selective Switch (WSS) (62) that is configured to shape ASE from the ASE source to form the one or more shaped ASE signals with one or two or multiple peaks and with associated frequency.

L'invention concerne des systèmes et des procédés consistant à entraîner la transmission d'au moins un signal d'émission spontanée amplifiée (ASE) conformé, à partir d'une source ASE (70), sur une fibre optique (58, 60) ; à obtenir un spectre reçu dudit signal ASE conformé à partir d'un récepteur optique (68) connecté à la fibre optique (58, 60) ; et à caractériser la fibre optique (58, 60) en fonction en partie d'au moins une jupe non linéaire et d'une profondeur d'immersion centrale dans le spectre reçu dudit signal ASE conformé au moins. Ledit signal ASE conformé au moins peut être mis en forme par la source ASE (70) couplée en communication à un commutateur sélectif en longueur d'onde (WSS) (62) configuré pour mettre en forme l'émission spontanée amplifiée (ASE) à partir de la source ASE pour mettre en forme ledit signal ASE mis en forme au moins, avec un, deux ou plusieurs pics et avec une fréquence associée.
