Abstract
Arrangement for transmitting an optical digital WDM signal over an optical transmission link or a passive optical network, the signal (S) including N optical channels matching a given optical frequency grid. The scheme includes supplying the WDM signal (S) to a near end of the optical transmission link or a near end of the passive optical network; receiving the WDM signal (S) 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(t)) by splitting and bandpass filtering the WDM signal (S) received; and converting the optical channel signals (s(t)) into electrical channel signals using direct optical detection. The signal (S) is created such that neighboring channel signals (s(t)) are orthogonally polarized and are conditioned with specific pre-distortion.
