A novel method for the gain and noise figure improvement of the reflection L- band erbium-doped amplifier via inserting a 980 nm pump laser diode in the input part was constructed. By selecting appropriate power ratio of the 980 and 1480 nm LD, compared to the configuration pumped with only 1480 nm LD, in the wavelength region from 1565 to 1615 nm. the gain enhances 1.5～9.9 dB and the noise figure decreases 1.3～9.4 dB for the small signal
