|Abstract: ||The fiber amplifier is a key enabling technology for high speed optical communication. The development of EDFA provide tremendous growth in communication system capacity.
The EDFA characteristics are analyzed for two different EDF length 7m and 13m, and two different wavelengths 1550nm and 1570nm. The gain and noise characteristics of amplifier is observed and compared with simulations.
The basic EDFA mathematical model is developed with Giles parameter by Matlab. The Gain Master software used to simulate the EDFA with different length, input power and pump powers.
The Optimum length of EDFA is 7m and use forward pumping configuration for reduce effect of noise. The EDFA in 1550nm has gain 34.47dB in 20μW input with 300mW pump power and noise figure is 4.5 dB.
The 5W amplifier use MOPA configuration. It has a EYCDFA followed by EDFA pre –amplifier. The optimum length selected for EYCDF is 6m with pump power of 18W.|
