摘要：
Flat gain with least noise figure (NF) is the backbone feature of super dense wavelength division multiplexing (SD-WDM) system. It indicates the good amplification in terms of high-quality factor, lowest bit error rate, and good rating output power. So, in this paper, we have mainly focused on the characteristics of proposed EDFA-TDFA hybrid optical amplifier (HOA) in terms of flat gain and noise figure for C-Band. Evaluation has done for 400 x 2.455 Gb/s SD-WDM system with channel spacing of 0.8 nm. Moreover, effect of proposed HOA has also observed with displacement of channel wavelength for evaluating the impact of different set of HOAs for analysis the same characteristics.
