In this study, the influence of highly nonlinear fibre (HNLF) in Fibre optical parametric amplifier (FOPA) gain has been done using numerical simulations. Results shows that nonlinear coefficient, γ affect the gain flatness of a FOPA. It was also found that amplifier gain increase with increase in fibre length. These results help in improving the transmission capacity of long haul system and dense wavelength division multiplexing (DWDM).
