Evaluation of Flat Gain with RAMAN-Thulium Doped Silica Glass Fiber Hybrid Optical Amplifier in Some Band Spectrum for Super Dense Wavelength Division Multiplexing System

摘要

The performance of RAMAN-TDSGF hybrid optical amplifier (HOA) has been examined in the context of gain and noise figure (NF) for 400 × 10 Gbps super dense wavelength division multiplexing (SD-WDM) system. Characteristics of this novel HOA has also compared with RAMAN-EDFA-RAMAN, RAMAN-EDFA and RAMAN-RAMAN HOA for the range of 1530 nm to 1665, and 1530 nm to 1586 nm respectively. Best rating in terms of maximum gain of 35.9 dB and noise figure of 3.2 dB have recorded from RAMAN-TDSGF HOA with the variation of 0.025 dB than the other HOAs. Moreover this paper also has shown the worst response from RAMAN-RAMAN HOA for super dense optical communication system.
