Performance of an Er{sup 3} + -doped fiber amplifier pumped by 0.98 {mu}m LD's is reported in detail. The highest signal gain of 37.8 dB at 30 mW pumping power was realized at a signal wavelength of 1.536 {mu}m. Furthermore, a high gain coefficient of 1.9 dB/mW was achieved, which was twice as efficient as that pumped by 1.48 {mu}m LD's.
