In this paper what we obtain is how we can achieve the same power level at the output irrespective of applying two different input signals having different wavelength at the input end without using any Automatic Gain Controller. In order to achieve that we are using two EDFA and special type of filter. In this an amplification is occurred for a signal passes through the core doped with erbium ion (Er+3) under the effect of pump, absorption, stimulated, and spontaneous emission. The new amplifier requires only a single pump laser. In the experiment, 980nm laser diode was used and the pump power was 100 mW over a wide input-power range of-30 to-10 dBm.
