Channel spectrum capacity is the main demanding issue for dense optical communication to increase more number of channels for increasing the transmission speed with least effect of optical dominating features which have resolved in this current research work for the first time for 80 × 12 dense wavelength optical communication system with power amplification from RAMAN optical fiber amplifiers. Further analysis has also done for getting the outcomes in terms of quality factor (Q-factor) and bit error rate (BER) for 80 channels with considering the channel spacing at 100 GHz, at 50 GHz, at 40 GHz, at 25 GHz, and at 20 GHz, respectively. Final conclusion is given with the recommendation that 100 GHz channel spacing is better to receive the most appropriate rating of Q-factor of 38 dB with BER of 3.3 × 10−10 for dense optical process.
