The dynamic range of an optical link in a network is determined by simultaneously transmitting signals from two network elements at first and second frequencies, which create a combined signal at a third frequency. The transmission power levels of selected network elements is successively increased until the measured power from the third frequency no longer changes in a predicatable manner, at which point the upper limit of the dynamic range of the optical link is determined.

Pour déterminer la plage dynamique d'une liaison optique dans un réseau, on transmet simultanément des signaux depuis deux éléments de réseau à une première et une deuxième fréquence, ce qui génère un signal combiné à une troisième fréquence. On augmente successivement les niveaux de puissance de transmission des éléments de réseau sélectionnés jusqu'à un point où la puissance mesurée à la troisième fréquence ne change plus de manière prévisible, point auquel on détermine la limite supérieure de la plage dynamique de la liaison optique.
