我们提出了共泵和反泵拉曼放大器的泵到信号相对强度噪声（RIN）传输特性的分析模型和测量。本文定量分析了共泵浦系统中色散噪声平均和反泵浦系统中不同传播方向的噪声平均。结果表明，非色散位移光纤和其他光纤之间的信号和泵浦波长的高色散给出了一个更大的潜力，用于共泵浦拉曼放大系统。
We present an analytical model and measurements of the pump to signal relative intensity noise (RIN) transfer characteristics of copumped and counterpumped Raman amplifiers. We give a quantitative analysis of noise averaging from chromatic dispersion in copumped systems and from different propagation directions in counterpumped systems. It is shown that nondispersion-shifted fibers and other fibers with high dispersion between the signal and pump wavelengths give a greater potential for use in copumped Raman amplified systems.
