Abstract (en)
[origin: WO9828826A1] The invention concerns a fibre amplifier with two amplifier stages (OV1, OV2) connected in series, a controllable optical attenuation member (OD) and an optical filter (OF) being connected between the amplifier stages. Both amplifier stages are controlled with respect to a constant amplification, and the optical attenuation member (OD) is controlled with respect to a constant output level.
