There is proposed an optical amplifier apparatus particularly for use in networks distributing signals by optical fibers, comprising first and second parallel optical branches (1, 2), the first optical branch (1) including optical amplifier means (5, 6) for amplifying digital signals and the second optical branch including optical amplifier means (7) for amplifying analogue signals, the optical amplifier means (5, 6) of the first optical path (1) being adapted to amplify bi-directional digital signals and the optical amplifier means (7) of the second optical branch (2) being adapted to amplify unidirectional analogue signals.
La présente invention concerne un dispositif d'amplificateur optique plus particulièrement destiné à des réseaux distribuant des signaux via des fibres optiques. Un tel dispositif d'amplificateur optique comporte deux ramifications optiques (1, 2). La première ramification (1) comporte des organes d'amplification optique (5, 6) permettant l'amplification des signaux numériques, la seconde ramification (2) comportant des organes d'amplification optique (7) permettant l'amplification des signaux analogiques. Les organes d'amplification optique (5, 6) de la première ramification optique (1) sont conçus pour amplifier les signaux numériques bidirectionnels, les organes d'amplification optique (7) de la seconde ramification optique (2) étant conçus pour amplifier les signaux analogiques unidirectionnels.
