本文分析了单模光纤系统中偏振噪声的产生机理,推导了单模光纤接头传输效率和偏振噪声信噪比的表达式以及最大最小信噪比的近似估计。理论分析和实验结果表明,实际系统中偏振噪声是可以忽略的。
In this paper, the generation mechanism of polarization noise in single-mode fiber system is analyzed. The expression of single-mode optical fiber connector transmission efficiency and signal-noise ratio of polarization noise and the approximate estimation of maximum and minimum signal-to-noise ratio are derived. Theoretical analysis and experimental results show that the actual system of polarization noise can be ignored.
