Within an optical ATM node, an ATM cell to be synchronized is sent into a segment of pre-determined length of an optical fibre with a high time dispersion, after having been associated, in a tunable wavelength converter, to an optical carrier with a wavelength that is different from that with which the cell itself was received and such that, as an effect of the transit in the fiber, the cell reaches the input side of a switching element of the node at a predetermined instant (Figure 2).
Dans un noeud optique MTA, une cellule MTA à synchroniser est transmise dans un segment de fibre optique de longueur prédéterminée ayant une grande dispersion temporelle après avoir été associée, dans un convertisseur de longueur d'onde accordable, à une porteuse optique ayant une longueur d'onde différente de celle à laquelle elle a été elle-même reçue. Comme conséquence de son passage dans la fibre, la cellule atteint l'entrée d'un élément de commutation du noeud à un instant prédéterminé (figure 2).
