Novel flattened gain using RAMAN-Erbium doped silica fiber hybrid optical amplifier for super dense wavelength division multiplexing system

Abstract

We have proposed a very advanced super dense wavelength division multiplexing (SD-WDM) system using RAMANErbium doped silica fiber optical amplifier (EDSFA) hybrid optical amplifier (HOA) in this paper. Performance is evaluated in term of flattened gain and noise figure for C-band. Effect of proposed hybrid optical amplifier also compared with EDFARAMAN, EDFA-SOA and SOA-SOA HOA for the same characteristics. Best rating gain of 37.5 dB with noise figure of 5.4 dB ever recorded from RAMAN-EDSFA HOA. It is also observed that out come from SOA-SOA HOA is not acceptable in term of noise figure of 9.1 dB for 400 x 10 GB/s SD-WDM system.
