Signal gain saturation characteristics of a 1·48μm wavelength LD pumped Er3+-doped fibre amplifier are experimentally investigated for two signal channels amplified around the gain peak wavelengths of 1·535μm and 1·551μm. The degree of gain saturation is uniquely determined by the total output power when the signal wavelengths are closely positioned. This feature is not suited to two-channel amplification for widely spaced wavelengths.
