We present analytically the effect of concentration of Er3+ and Yb3+ on the gain and noise figure characteristics of Er-Yb codoped/Raman hybrid amplifier (HA) at pump power of 28.5 dBm . The gain and noise figure are calculated at steady state conditions, neglecting ASE with 1m length of Er-Yb co-doped, 25 km Raman amplifier length and input signal power of -40 dBm in the signal wavelength range (1525 – 1610 nm). The maximum gain (53.92 dB at 1530 nm and 43.8 dB at 1600 nm) and minimum noise figure (3.48 dB at 1530 nm and 5.65 dB at 1600 nm) are obtained for the hybrid amplifier at 5.14×1025 m-3 Er concentration and 1×1026 m-3 Yb concentration , on the other hand the gain shows large values at end range of signal wavelength with the same input parameters listed above due to hybrid Raman amplifier with EYDFA so, a flat gain is observed in the all range of signal wavelength with higher band width..
