Performance analysis of EDFA physical model in optical fiber communication systems

To amplify a signal after a few kilometers, need an optical amplifier in optical communication systems. In this paper OSNR as a function of length of EDFA for physical model of EDFA is observed. Also measured the receive power for custom designed length at different wavelength and optimize the length of EDF (Erbium doped fiber). It is observed that at 980nm, EDFA with length 20 to 40m has highest OSNR and satisfactory power available. Similar results are found at wavelength 1550nm.
