CA 2353815

A WDM ring transmission system is provided whereby each optical signal is first dropped from the ring, supplied to an amplifier, and then input to an optical receiver. Typically, a filtering element is also provided either prior to or after the amplifier. The amplifier increases the power of the transmitted optical signal so that the optical signals can be transmitted over greater distances, and the filtering element minimizes any adjacent channel cross-talk light fed to the receiver. Moreover, since the amplifier only amplifies the dropped channel, excessive noise accumulation due to non-uniform spectral gain can be avoided. In addition, channels can be arbitrarily assigned to add/drop elements along the ring.

L'invention se rapporte à un système de transmission en anneau à multiplexage en longueur d'onde (WDM) ayant des voies amplifiées à extraction, dans lequel chaque signal optique est tout d'abord extrait de l'anneau, délivré à un amplificateur, puis transféré à un récepteur optique. Généralement, un élément de filtrage est également disposé avant ou après l'amplificateur. Ce dernier accroît la puissance du signal optique émis de sorte que les signaux optiques puissent être transmis sur de plus grandes distances, et l'élément de filtrage minimise tout rayonnement diaphonique sur les voies adjacentes à destination du récepteur. De plus, étant donné que l'amplificateur n'amplifie que la voie sur laquelle sont effectuées les extractions, il est possible d'éviter toute accumulation excessive de bruit due à un gain spectral non uniforme. En outre, les voies peuvent être arbitrairement associées à des éléments d'insertion-extraction le long de l'anneau.
