This paper has shown the analysis of 200 channels dense wavelength division multiplexing (DWDM) system with the data rate of 14 Gbps for attaining the flat gain for the channel spectrum from 1520 to 1640 nm. Analysis has also extended with the power amplification of erbium–ytterbium co-doped optical amplifier (EYBCDOWA) and Raman optical amplifier for the transmission distance of 120 km to mitigate the effect of crosstalk and bit error rate (BER). Final analysis has also recommended that this proposed system is capable to deliver the flat gain of 19.5 dB with minor variation of 0.95 dB to maintain the acceptable dense communication for long distance.
