摘要

PROBLEM TO BE SOLVED: To measure PMD of an optical fiber by a small amount of measurement data and operation processing.;SOLUTION: A linearly polarized optical pulse having a prescribed wavelength is allowed to enter one end side of the optical fiber 1, and its back-scattering light is received by a polarized light receiving part 26, to thereby acquire a Stokes parameter in each section of the optical fiber 1. A parameter calculation means 32 calculates parameters of each matrix in each section based on a model formula of the optical fiber 1 defined by a transfer function matrix and a scattering Meuller matrix and the acquired Stokes parameter. The first Jones matrix calculation means 33 determines the first Jones matrix in each section based on the calculated parameters, and the second Jones matrix calculation means 34 determines the second Jones matrix in each section having a different wavelength from the prescribed wavelength based on the calculated parameters. A polarization mode dispersion calculation means 35 calculates the polarization mode dispersion in an optional section of the optical fiber 1 based on the acquired two pairs of Jones matrices.;COPYRIGHT: (C)2005,JPO&NCIPI
