Abstract

La présente invention concerne une méthode et un dispositif de transmission WDM sur fibre optique à dualité de polarisation. La méthode de transmission utilise un codage IQ spécifique permettant de combattre les effets de la PDL. Les symboles de modulation à transmettre sur les états de polarisation des longueurs d’onde subissent une décomposition en valeurs réelles et valeurs imaginaires (220). Un vecteur réel composé par la concaténation de ces valeurs réelles et de ces valeurs imaginaires est ensuite construit. Une première transformation linéaire inversible, représentée par une matrice réelle dense, est appliquée (230) au vecteur réel ainsi obtenu pour fournir un vecteur réel transformé. Des symboles d’émission complexes sont formés par combinaison I/Q (240) des composantes du vecteur transformé, les symboles d’émission modulant ensuite les différents états de polarisation des canaux WDM. Fig. 2The present invention relates to a WDM transmission method and device over dual polarization optical fiber. The transmission method uses specific IQ coding to combat the effects of PDL. The modulation symbols to be transmitted on the polarization states of the wavelengths undergo a decomposition into real values and imaginary values (220). A real vector composed by the concatenation of these real values and these imaginary values is then constructed. A first invertible linear transformation, represented by a dense real matrix, is applied (230) to the real vector thus obtained to provide a transformed real vector. Complex transmission symbols are formed by combining I/Q (240) of the components of the transformed vector, the transmission symbols then modulating the different polarization states of the WDM channels.
