摘要：

In this paper, we have reported a very advanced hybrid optical amplifier (Raman-TDFF amplifier) for the 180 x 10 Gbps super dense wavelength division multiplexing sy stem with the channel spacing of 100 GHz. The performances of the model have been evaluated in terms of gain and noise figures for the C-band (from 1525 to 1565 nm). Gain flatness (>21 dB) is recorded with the least variation of 2.5 dB without using any cost effective technique. Further, the effect of the proposed hybrid optical amplifier has also been analyzed with slightly shifting the wavelength spectrum for the same feature.
