Abstract: In high-capacity WDM networks, achieving flat, broadband amplification without adding noise is crucial for spectral efficiency and reach. We propose a three-section dual-pump fiber optical parametric amplifier (FOPA) that places all channels on the same side of each pump wavelength to suppress SPM/XPM-induced impairments. By using three dispersion-shifted fibers (DSF₁ at 1550 nm, DSF₂ at 1550 nm, DSF₃ at 1568.2 nm) and appropriately tuned pumps at 1550 nm and 1568.2 nm, our design delivers 27 dB of gain flatness over a 58 nm span (1522-1580 nm) in simulations. Bit-error-rate (BER) measurements after 25 km single-mode fiber confirm sub-10⁻⁹ performance. Compared to prior dual- and multi-pump FOPAs, our unilateral channel allocation simplifies filtering and reduces nonlinear crosstalk, paving the way for practical, cost-effective ultra-wideband amplification.
