Abstract

We have used an interferometric technique to measure first- and second-order dispersion of a particular type of dispersion-shifted fiber. The values of $\ddot{\beta }$ and $\stackrel{⃛}{\beta }$ near the dispersion minimum are substantially the same as those of a conventional fiber except for being shifted from the 1.3-μm to the 1.5-μm wavelength range. We discuss the implications of this observation on the bandwidth of dispersion-shifted fibers.
