A gain-clamped erbium-doped fiber amplifier (GC-EDFA) for WDM optical packet-switching system

AbstractAim and scope of this study is to simulate the performance signature of optical inter satellite links based booster Erbium doped fiber amplifier (EDFA) and receiver preamplifiers. The study is simulated to demonstrated the effect of changing the propagation distances between satellites spacing based on the booster EDFA and receiver preamplifiers. Signal power amplitude, Max. Q factor, and min bit error rate are investigated against the input power variations.

AbstractThis paper has simulated the pump laser automatic signal control for erbium-doped fiber amplifier gain, noise figure, and output spectral power. Signal gain and noise figure are deeply studied in relation to laser pump power variations at operating pumping wavelengths of 980 nm and 1,480 nm for previous and proposed models. Similar to the study of the light signal to noise ratio, output power level and maximum Q factor are also simulated versus EDFA amplifier length at pumping power of 500 mW and different pumping wavelength by using the proposed model. The obtained results are better by using a pumping wavelength of 1,480 nm than a pumping wavelength of 980 nm. The optimum EDFA amplifier is 5 m, which gives better performance than other amplifier lengths.

Abstract Different fiber amplifiers such as semiconductor optical amplifier, erbium-doped fiber amplifier and erbium ytterbium-co-doped fiber amplifier (EYCDFA) are investigated for 16×40 GB/s wavelength division multiplexing system. Various performance parameters including Q-factor, bit error rate, jitter, eye opening and eye closure are observed and analyzed. It is reported that EYCDFA is a better choice among the tested amplifiers. The proposed system is also investigated in terms of transmission distance.
