ABSTRACT:
A process and apparatus for the optical transmission of a multiplex of a electrical carriers in which production takes place, from the electrical signal corresponding to the multiplex of electrical carriers, of an electrical asymmetrization signal, whose frequency spectrum is included in the unoccupied frequency range where the multiplex of electrical carriers is absent located in the lower part of the frequency spectrum of the multiplex of electrical carriers. The electrical asymmetrization signal is added to a delayed electrical signal corresponding to the multiplex of electrical carriers, and power modulation takes place of an optical source by the thus obtained electrical asymmetrical signal. The process and apparatus has application to optical fibre transmission systems.
