The Development of PMD and its Compensation Method

With the quickly development of fiber communication, PMD(Polarization mode dispersion) has became one of the key factor which limit high-bit rate system performance. In 1986, C.D.Poole[1] and other people found that if do not consider loss of SOP, two upright PSP will change along certain length SMF. In 1987, D.Andresciani and N.S.Bergano validate the theory of C.D.Poole each either. Late ninety of last century, statistical theory forming[2]. In the paper, we discuss the study of PMD, including statistics of PMD, measure technology, the affect of system by PMD, and PMD Compensation Method.
