We report signal amplification and output signal-to-noise ratio (SNR) for simultaneous four-channel amplification at C-band in the new type of erbium-doped fiber (EDF) having core glass compositions of zirconia-yttria-alumino-phospho-silicate (EDF-I). Performance of EDF-I is compared with two mostly used EDFs having core glass compositions of alumino-silicate (EDF-II) and germino-alumino-silicate (EDF-III). EDF-I produces the best result of maximum gain difference <; 2 dB with output SNR of >; 22 dB at input signal level of -30 dB·m/channel amplification.
