L'invention concerne un dispositif de transmission en large bande optique et un procédé de distribution, qui peuvent être, respectivement, utilisés ou mis en oeuvre pour des mises en réseau multimédia dans des pâtés de maison multiples. Selon l'invention, une fibre optique (101), qui constitue l'élément central relie un premier émetteur-récepteur (102) optique à un second émetteur-récepteur (103) optique. Avec le dispositif selon l'invention, on peut transmettre des flux de données entre un noeud de distribution (104) et un noeud d'utilisateur (105), avec une grande largeur de bande. La vitesse de transmission selon le procédé présenté atteint, normalement, 100 Mbs, tandis qu'avec une ligne de transmission électrique selon l'état de la technique on ne peut atteindre qu'une vitesse de transmission maximale de 10 Mbs avec la même longueur de transmission (500 à 1000 m).
