Abstract
Cette invention se rapporte à un appareil qui sert à mesurer les propriétés d'une fibre guide d'ondes optique et qui est dépourvu des diaphragmes, lentilles et miroirs généralement requis pour la mesure de certaines propriétés des fibres guide d'ondes. Cet appareil utilise un commutateur optique à l'extrémité d'émission de la fibre optique à tester et un autre commutateur optique à l'extrémité de sortie de la fibre optique à tester. Ces commutateurs préservent la distribution de puissance de mode, en particulier la taille du spot, de la lumière les traversant. Cet appareil peut servir à mesurer la largeur de bande ou l'atténuation d'une fibre guide d'ondes multimode, deux propriétés qui sont affectées par la distribution de puissance de mode émise et détectée.
