对基于邦加球的偏振模色散 (PMD)测量方法进行了充分的研究 ,利用输出偏振态的随机性 ,提出了一种比较简单而实用的算法 ,利用这种算法 ,对 11km单模光纤和 1 6 7m长保偏光纤进行了测量 ,实验证明这种算法具有很好的实用价值。
Based on Bunge-ball’s polarization mode dispersion (PMD) measurement method has been fully studied, the use of random output polarization state, put forward a relatively simple and practical algorithm, the use of this algorithm, the 11km single-mode fiber and 1 6 7m long polarization-maintaining fiber was measured, experiments show that this algorithm has good practical value.
