With the development of optical fiber communication technology, more and more in-depth study of polarization mode dispersion, the reason is that the fiber polarization mode dispersion of ultra-high speed optical fiber transmission performance of digital systems can not be ignored. The majority of optical fiber 更多：https://www.bmcx.com/ , optical cable manufacturers and telecommunications users are made more in-depth study of the optical fiber pmd reference itu-t develop the corporate standards, into the control range of the optical performance.

With the development of optical fiber communication technology, more and more research on polarization mode dispersion, the reason is the optical fiber polarization mode dispersion on transmission performance of ultra high speed digital fiber systems has a serious impact. Currently vast numbers of optical fibre and cable manufacturers and Telecom users are on fiber PMD for more in-depth study 更多：https://www.bmcx.com/ , taking into account ITU-T has established appropriate business standards, control of fibre performance indicators were included.

Along with the development of the optical fiber communication technology, people of optical polarization mode dispersion research work more and more thorough, investigate its reason is the polarization mode dispersion on optical fiber optical fiber transmission of digital system superhigh speed performance has the effect of cannot be ignored. At present the optical fiber 更多：https://www.bmcx.com/ ,Cable manufacturers and users to optical fiber telecom PMD for a more in-depth study, at the same time with reference to ITU-T formulated relevant enterprise standards, included the control range of optical fiber performance index.
