we propose a new model of optoelectronic delay device based on non-local non linearity which highlights the enhancement of security level in chaos communications. The model principle consists in generating chaotic c arriers from two wa velengths and transmitting only the main driving the message through the optical fibre. By the means of synchronization error and the largest conditional Lyapunov ex ponent we establish the conditions filled by the non-transmitted wavelength to preserve complete synchronization.
