Abstract
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 bidirectional digital signals and the optical amplifier means (7) of the second optical branch (2) being adapted to amplify unidirectional analogue signals.
