Abstract

L'invention concerne un procédé destiné à réguler une puissance de sortie d'amplificateur dans un réseau de communication optique doté d'une fonction d'insertion-extraction. Un premier paramètre de transmission et un second paramètre de transmission sont déterminés au niveau d'un premier amplificateur. Dans un mode de réalisation, le premier paramètre de transmission est un rapport signal sur bruit exprès composite, le second paramètre de transmission étant un rapport signal sur bruit composite. La puissance de sortie totale d'un amplificateur aval est ajustée en réponse au premier paramètre de transmission et au second paramètre de transmission. L'invention concerne également un système destiné à la mise en oeuvre de ce procédé.
