Enhancing Optical Signal-to-Noise Ratio in Terrestrial Cascaded EDFAs Fiber Optic Communication Links using Hybrid Fiber Amplifier
In this paper, we propose calculating models of Terrestrial DWDM cascaded EDFAs Fiber Optic Communication Links using Hybird Fiber Amplifier (HFA) including combination of Distributed Raman Amplifier (DRA) and EDFA, and build algorithm charts to optimize parameters including signal power per channel launched fiber, EDFAs gain, pump power of Raman amplifier for improving optical Signal-to-Noise ratio (OSNR) at the end of link. Then, algorithm-based numerical calculating (MathCAD program) is applied in typical system (WDM Nation-wide links in Vietnam). Optimized results show that the OSNR can be increased by (1-5) dB comparing with that in cases of parameters chosen by experience way.
