ABSTRACT:
A method and apparatus for non-destructively measuring dispersion-zero wavelengths along an optical fiber makes use of a four-photon-mixing technique to generate mixed, amplified, idler signals at positions or ranges along the fiber. The dispersion zero wavelengths are then calculated using the wavelengths of the generated idler signals after taking into account inaccuracies due to higher order phenomena.
