【Abstract】 Based on two stage erbium fiber and optical loop couping configuration, 980 nm and 1480 nm LD pumped erbium doped fiber amplifier (EDFA) has been developed. The characteristics of EDFA have investigated experimentally at wavelength of 1553 nm. Results show that the small signal gain, noise figure and maximum output power are of 42.8 dB, 4.4 dB and 15.2 dBm, respectively.更多还原
