Paper Abstract

The accuracy of chromatic dispersion measurements made using a phase-shift technique utilizing only three lasers (with wavelengths in a neighborhood of the zero-dispersion wavelength) is calculated. It is shown that by defining and measuring the center wavelengths of the three lasers accurately, a measurement accuracy of better than ± 1.5 nm in the zero-dispersion wavelength (λo) and better than ± 0.007 ps/nm-km in the zero-dispersion slope (SO) can be obtained for long lengths of conventional fiber with λo near 1310 nm. This corresponds to an accuracy of better than ± 0.1 ps/nm-km in the dispersion at a wavelength of 1285 nm. The accuracy of extrapolating these 1300 nm dispersion results to 1550 nm using a three-term Sellmeier model is also calculated and compared with experimental results.
