In this paper we have designed a Fiber Optical Parametric Amplifier (FOPA) based on octagonal lattice TeO₂ highly nonlinear photonic crystal fiber (PCF). The system needs a tunable pump laser with appropriate pump laser power and wavelength co-propagation along the nonlinear fiber with data signal. A typical gain value of 8-12 dB over a wide bandwidth of 200-300 nm – including C band – has been achieved by using a short length of the PCF. In the following, we have investigated the effect of pump wavelength, pump power and fiber length variation on FOPA gain. We have proofed that FOPA gain has increased by fiber length and pump power increment. However, consumedly increment of these two results in gain decrement and data lost.
