    • A method of evaluating the Polarization Mode Dispersion (PMD) of an optical fiber by arranging the optical fiber at substantially zero tension on a surface, propagating prescribed evaluation optical signals along the optical fiber, measuring fiber Differential Group Delay (DGD) values in response to the evaluation optical signals, repeating at least once the acts of propagating and measuring, each time preliminarily inducing a change in a mode coupling of the fiber, and determining the fiber PMD on the basis of a calculated DGD average value. Changes in the polarization mode coupling of the fiber are induced by, moving at least a section of the fiber substantially orthogonally to the surface. An improved PMD evaluation apparatus includes a fiber arrangement surface adapted to have a fiber under test arranged thereon at substantially zero tension, and, operatively associated with the fiber arrangement surface, a fiber moving device activatable for moving the at least a section of the fiber substantially orthogonally to the fiber arrangement surface.
    • 一种通过将光纤布置在表面上基本为零张力的光纤来评估光纤的偏振模色散(PMD)的方法,沿着光纤传播规定的评估光信号,响应于光纤的差分组延迟(DGD)值 评估光信号,每次重复至少一次传播和测量的动作,每次预先引起光纤的模式耦合的改变,并且基于所计算的DGD平均值来确定光纤PMD。 纤维的偏振模式耦合的变化是通过将纤维的至少一部分基本上垂直于表面移动而引起的。 一种改进的PMD评估装置包括纤维布置表面,该纤维布置表面适于具有基本上零张力的被测试纤维,并且与纤维布置表面可操作地相关联;纤维移动装置,其可激活以基本上移动纤维的至少一部分 与纤维布置表面正交。
