Comparative Characteristics between L-Band EDFA, L-Band EDFA Utilising Single FBG and Dual Stage L-Band EDFA Utilising Dual FBG Configurations

The development was conducted with three configurations of L-Band EDFA, L-Band EDFA utilising Single FBG and Dual Stage L-Band EDFA utilising Dual FBG. The configurations utilising the FBG using 35 meter M-12 Fibercore EDF as the gain medium to amplify the input signal power in the L-band region. The gain enhancement has shown by the Dual Stage L-Band EDFA utilising Dual FBG by injecting low input signal power of -10 dBm. The flat amplitude of OSNR at 33.358 dB was produced at injected wavelength from 1570 nm to 1605 nm.
