A novel compensation method for temperature-dependent gain tilt of L-band erbium-doped fiber amplifier(L-EDFA) is proposed, in which the attenuation between stages is the only parameter to be adjusted. Asimple linear relationship between the attenuation and the erbium fiber coil temperature was derivedtheoretically. When the erbium fiber coil temperature cycles from 26 to 70℃, the gain tilt variationless than 0.3 dB is achieved experimentally by adjusting only the pre-inserted variable optical attenuator(VOA).
