Abstract
The amplification characteristics of an Er3+-doped tellurite-based fibre amplifier (EDTFA) with 980 nm band pumping are described. The optimum pump wavelength and length of the newly developed EDTF are investigated in order to obtain both a low noise figure and a high gain simultaneously. We realise a low noise figure of less than 4.5 dB with a pump wavelength of 976.5 nm and a 0.4 m EDTF.
