A reflective long-wavelength-band erbium-doped fiber amplifier (L-band EDFA) with enhanced gain and improved noise figure is demonstrated. By utilizing a short length of erbium-doped fiber (EDF) before an optical circulator (OC), the population inversion at the input of this EDFA is intensified, whi
