摘要
研究了光纤拉曼放大器中双重瑞利散射噪声的特性,提出了在考虑拉曼光放大作用时,双重瑞利散射噪声的表达式.给出了在加入隔离器进行抑制后,双重瑞利散射噪声的计算方法,并进行了模拟分析,得出了放置隔离器的最佳位置.
Abstract
The amplified double Rayleigh backscattering noise (DRB) in a optical fiber Raman amplifier is analyzed and the related expressions are presented. Calculation is performed for the case that an optical isolator is inserted to suppress the DRB noise. Simulation results are given and the optimal position for the isolator is determined.
