In this paper we have examined the performances of 180×10 Gbps super dense wavelength division multiplexing (SD-WDM) system using the RAMAN–thulium-doped tellurite fiber amplifier (TDTFA) hybrid optical amplifier (HOA) with the channel spacing of 50 GHz in S+C+L band. Accepted rating flattened gain of 39.21 dB with the noise figure less than 5 dB is archived with the dual-pumping ( power level of 500 mW at 980 nm and at 1100 nm for RAMAN optical amplifier and similar, power level of TDTF amplifier is set to 500 mW and 350 mW at 1150 nm) technique. The effect of the proposed hybrid amplifier is evaluated in terms of gain and noise figure without using any coast effective technique. The outcome from the proposed model is also compared here with the existing optical amplifier.
