Abstract

La présente invention est relative à la technique des fibres optiques et concerne plus particulièrement un atténuateur optique fixe insérable entre des fibres optiques. Cet atténuateur optique comporte un milieu atténuateur 1, deux lentilles à faces planes et gradient d'indice 2, 3, alignées et séparées par le milieu atténuateur 1, et deux raccords à fibre optique disposés de part et d'autre de l'ensemble formé par les lentilles 2, 3 et le milieu atténuateur 1. Il s'utilise comme adaptateur de niveau aussi bien entre une source de rayonnement lumineux et un équipement qui lui est raccordé par fibre optique que dans des appareils de test, de calibration ou de mesure pour systèmes fibres optiques.
