Non-Zero Dispersion-Shifted Fiber
Dispersion shifted fiber (DSF) was used for the first optically repeated systems. Quickly non-zero dispersion shifted fiber (NZDSF) was selected to allow WDM transmission.
Non-zero dispersion-shifted fiber
Non-zero dispersion-shifted fiber (NZDSF), specified in ITU-T G.655, is a type of single-mode optical fiber which was designed to overcome the problems of dispersion-shifted fiber.
ITU-T Rec. G.655 (03/2003) Characteristics of a non-zero dispersion
This Recommendation describes a single-mode fibre with chromatic dispersion (absolute value) that is greater than some non-zero value throughout the wavelength range of anticipated use in the 1550
Nonzero-dispersion-shifted fiber: The choice for DWDM
The way to reduce four-wave mixing, therefore, is to produce a nonzero dispersion-shifted fiber with a zero-dispersion wavelength outside the normal operating range of the EDFA.
