Chromatic dispersion distribution measurement apparatus and method for the same

摘要

A chromatic dispersion distribution measurement apparatus for calculating a chromatic dispersion distribution in an optical communication path under test, includes an intensity ratio calculation unit for calculating an intensity ratio of a first light and a second light that are reflected from an optional position of the optical communication path under test and propagated to an incident end of the optical communication path under test by taking the same propagation time. A chromatic dispersion value calculation unit is provided for calculating a chromatic dispersion value in the optical communication path under test in accordance with the intensity ratio calculated by the intensity ratio calculation unit.
