Abstract

In this paper, a nondestructive measurement technique, which uses a four wavelength bidirectional optical time domain reflectometer (OTDR) to measure the chromatic dispersion distribution along an optical fiber transmission system, has been presented. A new formulation has been developed to enhance the correction factor, which leads to an improvement in the measurement results of a pre-existing method and the obtained experimental results are in good agreement with those obtained by the interferometric technique.
