dispersion-shifted fiber
A singlemode optical fiber that has been designed to reduce chromatic dispersion. The fiber core is fabricated in several layers with different refractive indices running in parallel throughout its length. Zero-dispersion-shifted fiber has zero chromatic dispersion at 1550 nm. It is no longer manufactured, because it causes interference in WDM transmission. Nonzero-dispersion-shifted fiber is designed for WDM. It has zero dispersion near 1500 nm and beyond 1600 nm, which provides lower dispersion in the 1550 nm range. See graded-index fiber, step index fiber and dispersion.

LEAF fiber, the most widely-deployed non-zero dispersion shifted fiber (NZ-DSF) in the world, has a patented large effective area and moderate dispersion to allow higher levels of power to be transmitted through the fiber than standard NZ-DSFs, minimizing the non-linear effects that degrade system performance.
