Title (EN) METHOD AND APPARATUS FOR TRANSMISSION OF TWO MODULATED SIGNALS VIA AN OPTICAL CHANNEL
(FR) PROCÉDÉ ET APPAREIL DE TRANSMISSION DE DEUX SIGNAUX MODULÉS PAR UN CANAL OPTIQUE
Abstract: front page image
(EN)The arrangement includes a transmitter (1-6) with two optical sources (1, 2) generating two optical carrier signals (L1, L2) having different frequencies. The optical carrier signals (L1, L2) are combined and divided in a first coupler (2) and fed to carrier signal inputs of two modulators (4, 5). The mixed carrier signals (L1 + jL2, jL1 + L2) are separately modulated by two modulation signals (a(t)) and (b(t)) and the modulated signals ((A1 +jA2), (jB1 +B2)) are combined in a first combiner and emitted as transmission signal (X(t)). Only on demodulator is necessary to regain the modulation signals (a(t), b(t)).
(FR)L'invention porte sur un agencement qui comprend un émetteur (1-6) avec deux sources optiques (1, 2) générant deux signaux porteurs optiques (L1, L2) ayant des fréquences différentes. Les signaux porteurs optiques (L1, L2) sont combinés et divisés dans un premier coupleur (2) et appliqués à des entrées de signal porteur de deux modulateurs (4, 5). Les signaux porteurs mélangés (L1 + jL2, jL1 + L2) sont séparément modulés par deux signaux de modulation (a(t)) et (b(t)) et les signaux modulés ((A1 + jA2), (jB1 + B2)) sont combinés dans un premier combineur et émis en tant que signal de transmission (X(t)). Un seul démodulateur est nécessaire pour récupérer les signaux de modulation (a(t), b(t)).
