7、MD特性的检验。2引用标准下列标准所包含的条文，通过在本标准中引用而构成为本标准的条文。在标准出版时，所示版本均为有效。所有标准都会被修订，使用本标准的各方应探讨使用下列最新版本的可能性。GBfr15972.1-1998光纤总规范第1部分:总则3定义本标准使用下列定义。3.1偏振模色散(polarizationmodedispersion)偏振模色散是两个正交偏振模之间的差分群时延(DGD)，它在数字系统中引起脉冲展宽，在模拟系统中引起信号失真。3.2主偏振态(principalstateofpolarization)

8、对于在给定时间和光频上应用的单模光纤，总存在着两个称之为主偏振态(PSP)的正交偏振态。如果当一准单色光仅激励一个PSP时，不会发生由于PMD引起的脉冲展宽;当一准单色光均匀激励这两个PSP时，将发生由于PMD引起的最大脉冲展宽。光纤输出的PST,是两个正交偏振态。当输入光波频率稍微变化时，输出偏振并不改变，相应的输入正交偏振态是
