摘要

我们描述了一个相位敏感放大器(PSA)在80km光纤跨度后，在非线性传输体制下携带单个DQPSK通道。对于EDFA和基于PSA的系统，随着信道内非线性失真的增加，系统的惩罚是相似的，这表明PSA的灵敏度优势仍然存在于非线性传输中。

Phase-sensitive amplified optical link operating in the nonlinear transmission regime

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 remain with nonlinear transmission.
