Support of Dispersion-Shifted Single-Mode Fiber (ITU G.655
and G.656)
and G.656)
PB530841
This product bulletin describes the support and benefits of dispersion-shifted single-mode fiber specified in
ITU G.655 and G.656 standards. These fibers are also referred to as nonzero dispersion-shifted fibers
(NZDSF).
For detailed information about fiber types, also refer to the document at

.
Chromatic Dispersion and Wavelength Dependency
The most commonly deployed single-mode fiber cables are those defined in ITU G.652. These fibers are optimal for
optical transmissions in the 1300-nm window and also used for transmissions in the 1550-nm window, including
CWDM and DWDM applications. ITU added support for NZDSF in Recommendations G.655 and G.656. These
fibers are advantageous for 1550-nm and WDM applications as their “zero dispersion” is close to the transmission
wavelength, resulting in less chromatic dispersion cumulated along the optical path.
