Abstract

L'invention concerne un système de guide d'ondes optiques permettant de protéger des fibres actives contre l'altération et l'interception de données dans des liaisons de communication à fibres optiques. La liaison de communication comprend un guide d'ondes (1000) qui s'étend d'une implantation à une autre, afin de transmettre un signal de données. Un émetteur de données (20) lance le signal de données dans la fibre (1000), et un récepteur de données (22) reçoit ledit signal. Un émetteur de signal de détection (40) lance un signal de détection dans la fibre (1000), et un récepteur de signal de détection (42) reçoit ledit signal pour ladite fibre (1000). Les émetteurs (20, 40) sont couplés à la fibre (1000) à l'aide d'un coupleur (30) de multiplexage/démultiplexage de longueurs d'ondes, via des bras d'entrée (76, 66) du coupleur (30). Les signaux sont transférés aux récepteurs (22, 42) par un autre coupleur (32) de multiplexage/démultiplexage, via des bras d'entrée (7c, 6c). Les coupleurs (30, 32) garantissent que les signaux sont combinés avec une perte de puissance minimum, et sont séparés afin d'être transmis aux détecteurs également avec une perte de puissance minimum, tous les signaux de données étant sensiblement transmis au récepteur (22) et tous les signaux de détection étant transmis au récepteur (42).
