The invention concerns a method of connecting a subscriber unit (12) to a fiberoptic communication network (14) via a fiberoptic interface device (30) adapted to function as an interface device (30) in a coarse wavelength division multiplex (CWDM) system. The interface device (30) comprises an electric circuit arrangement (32) and a first (34) and a second (36) receiving section adapted to receive transceiver modules (24, 70). According to the method, an opto-electric transceiver module (24) is arranged in said first receiving section (34) and connected to said fiberoptic communication network (14). A first electric transceiver module (70) is provided and arranged in said second receiving section (36). The interface device (30) is connected, via said electric transceiver module (70), to said subscriber unit (12) via electrical conduction paths (82, 86). The invention also concerns a method of testing the function of said interface device (30).

L'invention concerne un procédé de connexion d'une unité d'abonné (12) à un réseau de communications à fibre optique (14) via un dispositif d'interface de fibre optique (30) conçu pour fonctionner en tant que dispositif d'interface (30) dans un système de multiplexage spectral grossier (CWDM). Le dispositif d'interface (30) comprend un arrangement de circuit électrique (32) et des première (34) et seconde (36) sections de réception adaptées à recevoir des modules d'émission-réception (24, 70). Selon le procédé, un module émetteur-récepteur optoélectrique (24) est disposé dans la première section de réception (34) et connecté au réseau de communication par fibre optique (14). Un premier module émetteur-récepteur électrique (70) est mis en oeuvre et disposé dans la seconde section de réception (36). Le dispositif d'interface (30) est connecté, via le module émetteur-récepteur électrique (70), à l'unité d'abonné (12) via des voies de conduction électrique (82, 86). L'invention concerne aussi un procédé de test du fonctionnement du dispositif d'interface (30).
