Abstract

The invention relates to a method for transmitting an optical digital WDM signal over an optical transmission link or a passive optical network, the optical WDM signal (S WDM ) including N optical channels matching a given optical frequency grid, the method comprising the steps of: supplying the WDM signal (S WDM ) to a near end of the optical transmission link (5) or a near end of the passive optical network; receiving the WDM signal (S WDM ) at a far end of the optical transmission link or at one or more far ends of the passive optical network; separating the optical channel signals (s i (t)) by splitting and bandpass filtering the WDM signal (S WDM ) received; and converting the optical channel signals (s i (t)) into electrical channel signals using direct optical detection. The method is characterized in that the optical WDM signal (S WDM ) is created such that neighboring channel signals (s i (t)) are orthogonally polarized. Moreover, the invention relates to an optical WDM transmitting device (9) and to an optical WDM transmission system implementing this method.
