Abstract
La présente invention concerne un procédé et un appareil (10) d'émission (12, 14) et de réception (24, 26) de sous-porteuses d'hyperfréquences/RF multiples sur une seule longueur d'onde optique dans une liaison optique. Ce procédé consiste à moduler un groupe de plusieurs fréquences de sous-porteuses d'hyperfréquences/RF avec un signal de communication respectif et à moduler une onde porteuse optique avec la pluralité de fréquences sous-porteuses d'hyperfréquences/RF modulées. En outre, cette invention consiste à détecter la pluralité de sous-porteuses d'hyperfréquences/RF de l'onde porteuse optique et à mélanger (102) ces sous-porteuses avec une première fréquence d'oscillateur local (LO) pour créer une nouvelle fréquence IF hétérodyne au-dessus du composant à fréquence la plus élevée du spectre du signal modulé des sous-porteuses détectées, à filtrer ensuite la fréquence de sous-porteuse d'hyperfréquences/RF de la pluralité de sous-porteuses d'hyperfréquences/RF détectées en utilisant un filtre passe-bande (106), à une fréquence IF centrale de la nouvelle fréquence IF et mélanger la sous-porteuse d'hyperfréquence/RF avec la fréquence d'un second oscillateur local (LO), (108) pour obtenir une fréquence de différente à une fréquence centrale voulue en vue de la propagation dans l'élément de réseau ultérieur.
