Abstract

The dependence of pump wavelength for the amplification characteristics of a Er3+-doped fiber amplifier (EDFA) has been reported for 0.8, 0.98, or 1.48μm band, to date now most of long-wavelength-band (L-band) EDFA are using these pump bands [1]. In this paper, 1.53μm band is proposed and intensively investigated as new pump wavelength of L-band EDFA for the fist time Power conversion efficiency (PCE), gain coefficient and noise figure (NF) for pumping efficiency were measured and compared with 1.48μm pumped L-band EDFA.
