Title (EN) METHODS AND APPARATUS FOR OFDR INTERROGATOR MONITORING AND OPTIMIZATION
(FR) PROCÉDÉS ET APPAREIL POUR LA SURVEILLANCE ET L'OPTIMISATION D'UN INTERROGATEUR OFDR
Abstract:
(EN) Example embodiments add an optical amplifier to an multi-channel, continuously swept OFDR measurement system, adjust amplified swept laser output power between rising and falling laser sweeps, and/or utilize portions of a laser sweep in which OFDR measurements are not typically performed to enhance the integrity of the OFDR measurement system, improve the performance and quality of OFDR measurements, and perform additional measurements and tests.
(FR) Des formes de réalisation exemplaires ajoutent un amplificateur optique à un système de mesure OFDR multicanaux à balayage continu, règlent la puissance de sortie laser balayée et amplifiée entre des balayages laser ascendant et descendant, et/ou utilisent des parties d'un balayage laser dans lequel des mesures OFDR ne sont pas habituellement mises en œuvre pour renforcer l'intégrité du système de mesure OFDR, améliorent les performances et la qualité des mesures OFDR, et exécutent des mesures et des essais additionnels.
