To fulfill the needs of current bandwidth hungry internet services, optical amplifiers are required that can provide better Gain, less crosstalk and large bandwidth. In order analyze the effects of different physical parameters such as amplifier’s fiber length, core radius, pump power and pump wavelength in a single stage C+L band erbium doped fiber amplifier, a system 32 channel system is proposed at low input power levels. Gain flatness of 4.59 dB is achieved without using any external components and multiple stages of EDFAs in C+L band. we proposed a single stage low cost C+L band EDFA amplifier incorporating fiber bragg gratings (FBG). It is observed that FBG incorporated system exhibits improved gain flatness (2.43 dB) as compared to without FBG system (4.59 dB). Crosstalk is major degrading effect in WDM incorporated EDFA systems. It is perceived that proposed EDFA-FBG offers low crosstalk. It is noteworthy that gain fatness of 2.43 dB is achieved without using any costly components such as isolators, GFFs and multiple stages of EDFAs.
