Abstract :
Summary form only given. The dependence of pump wavelength for the amplification characteristics of a Er/sup 3+/-doped fiber amplifier (EDFA) has been reported for 0.8, 0.98, or 1.48 /spl mu/m band, to date now most of long-wavelength-band (L-band) EDFA are using these pump bands. In this paper, 1.53 /spl mu/m 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 1.48 /spl mu/m pumped L-band EDFA.
