PMD CHARACTERISTICS MEASURING METHOD OF OPTICAL FIBER, LINE DRAWING METHOD, ABNORMAL PLACE SPECIFYING METHOD AND OPTICAL FIBER TRANSMISSION PATH CONSTRUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a novel measuring method, an optical fiber line drawing method and an optical fiber transmission path construction method, capable of precisely measuring the optical fiber characteristics regarding a PMD.;SOLUTION: A Brillouin gain spectrum BGS is generated in a plurality of positions in the longitudinal direction of a measuring object optical fiber by BOCDA, and PMD characteristics are calculated, based on the Brillouin gain variation in respective measuring positions of the BGS.;COPYRIGHT: (C)2008,JPO&INPIT
