METHOD FOR MEASURING POLARIZATION CHARACTERISTICS OF OPTICAL FIBER, DRAWING METHOD, METHOD FOR IDENTIFYING ABNORMAL POINT, AND METHOD FOR CONFIGURING OPTICAL FIBER TRANSMISSION LINE |
摘要 |
<p>The present invention relates to a measuring method, etc., comprising a structure for accurately measuring optical characteristics such as PMD of an optical fiber. The measuring method is a technique for measuring polarization characteristic distributions along the longitudinal direction of the optical fiber as a measuring object by using BOCDA, and by propagating probe light and pumping light opposite in the optical fiber, BGS is generated at a plurality of respective measurement positions. Then, based on Brillouin gain fluctuations at the respective measurement positions, polarization characteristic distributions are calculated.</p> |
