Abstract
It is shown that AM signals introduce travelling inversion waves in the Er-doped fibre amplifier. A formula for the induced distortion is found. Especially for Er-doped fibres with high numerical aperture the distortions may reach magnitudes which are problematic in relation to AM-FDM optical video links.
