提出了一种测量光纤链路中全局偏振相关损耗（PDL）的单端技术。在这种技术中，被测光纤链路的终端光纤部分需要是纯双折射的。然后，全局PDL将由终端光纤段中的最大往返PDL确定。在实践中，可以通过测量对应于四个特定输入偏振态的瑞利后向散射光功率来获得往返PDL。实验结果证实了所提出的技术的有效性。
A single-ended technique is proposed to measure the global polarization-dependent loss (PDL) in an optical fiber link. In this technique, the terminal fiber section of the fiber link under test is required to be purely birefringent. Then, the global PDL will be determined by the maximum round-trip PDL in the terminal fiber section. In practice, the round-trip PDL can be obtained by measuring Rayleigh backscattering optical powers corresponding to four specific input polarization states. Experimental results confirm the validity of the proposed technique.
