Analysis of Novel 15Gbps WDM–FSO System Employing Hybrid Amplifier Under Various Weather Conditions

This paper presents high-capacity WDM (Wavelength Division Multiplexing)-based FSO system which utilizes two EDFAs (Erbium-Doped Fiber Amplifiers).It is used for long-distance transmission as a booster amplifier and SOA (Semiconductor Optical Amplifier) as a pre-amplifier. The proposed system supports 15Gbps transmission over optimized link length on various weather conditions, i.e., haze, light rain, medium rain, and heavy rain. This novel system provides Q-factor and BER of 17.55, 2.5e-69, respectively, for heavy rain conditions, whereas the conventional system provides Q-factor and BER of 9.14, 1.55e-20, respectively, for same weather condition. This paper increases Q-factor and BER, respectively, for heavy rain condition.
