摘要
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。
The method of Poincare Sphere to measure the polarization mode dispersion (PMD) has been studied in the paper. Based on the statistical character of the output states, a simple and practical arithmetic to calculate the differential group delay (DGD) with the output states of polarization was put forward. With this arithmetic, the PMD of a 11 km long single mode fiber and a 1.64 m long polarization maintain fiber have been calculated, and the feasibility of the arithmetic is confirmed.
