Abstract (40-Word Limit): We characterize a phase-sensitive amplifier (PSA) after an 80km fiber span, carrying a single DQPSK channel in the nonlinear transmission regime. The system penalty with increasing intra-channel nonlinear distortion is similar for EDFA and PSA based systems, indicating that the PSA sensitivity advantage may remain with nonlinear transmission.
