最近出现的掺铋光纤放大器（BDFAs）提供了在O波段光谱区域中长距离传输高速WDM信号的可能性，从而极大地增强了利用这些波长的系统的范围。在本文中，我们提出了一个全面的实验研究的几个基本特性的O-波段BDFA基于磷硅酸盐光纤，包括频率相关的噪声系数，增益倾斜（静态和动态），瞬态响应，和偏振相关的增益。我们讨论了我们的研究结果及其影响BDFA技术在高比特率多通道系统中的使用。
The recent emergence of bismuth-doped fiber amplifiers (BDFAs) offers the potential to transmit high-speed WDM signals over long distances in the O-band spectral region, thereby greatly enhancing the scope of systems utilizing these wavelengths. In this paper, we present a comprehensive experimental study on several basic characteristics of an O-band BDFA based on a phosphosilicate optical fiber, including the frequency-dependent noise figure, gain tilt (static and dynamic), transient response, and polarization dependent gain. We discuss our findings and their implications on the use of BDFA technology in high bit-rate multichannel systems.
