| Abstract: | The method and processes for designing high-gain, low-noise and gain-flattened with wide bandwidth two-stage erbium-doped fiber amplifier (EDFA) using for wavelength division multiplexing (WDM) system are given. By optimization of EDFA parameters, a high-gain, low-noise and gain-flattened with wide bandwidth two-stage EDFA was developed and achieved. The EDFA has a ?0.325 dB flattening gain in 36.6 nm bandwidth from 1524.8 nm to 1561.4 nm, a high output power more than 15 dBm when 0 dBm 1550 nm signal is input and a noise figure lower than 5 dB. |
