Title
(EN) DISTRIBUTED FIBER SENSING INTERROGATOR WITH DETACHABLE END
(FR) INTERROGATEUR À DÉTECTION DE FIBRE DISTRIBUÉE À EXTRÉMITÉ DÉTACHABLE
Abstract
(EN)
Aspects of the present disclosure describe systems, methods and structures for distributed fiber sensing systems including interrogator and attached fiber in which the interrogator includes a common line card and function-specific, pluggable front end in which the line card is configurable and supports different signal processing paths and automatically senses the front-end type and uses corresponding firmware/software or signal processing path(s) to process sensed data.
(FR)
Des aspects de la présente invention concernent des systèmes, des procédés et des structures de systèmes de détection de fibre distribuée comprenant un interrogateur et une fibre rattachée, l'interrogateur comprenant une carte de ligne commune et un frontal enfichable spécifique à la fonction. La carte de ligne est configurable, prend en charge différents trajets de traitement de signal, détecte automatiquement le type de frontal et utilise un micrologiciel/logiciel ou un/des chemin(s) de traitement de signal correspondants pour traiter des données détectées.
