At 1310nm the material dispersion and waveguide dispersion are equal and opposite, which gives almost zero total dispersion at this point. Hence the fiber is called DCF as material and waveguide dispersion compensate each other. At 1550nm minimum attenuation is achieved.

Historically, singlemode optical fiber was designed with the minimum Chromatic dispersion point at Later, when transmission moved to 1550nm, dispersion “shifted” fibers were developed for very This was termed “dispersion flattened” fiber. Today, transmission wavelengths are all over the
Dispersion: Rainbows and Prisims. Dispersion is defined as the spreading of white light into its full spectrum of wavelengths. Dispersion occurs whenever there is a process that changes the direction of light in a manner that depends on wavelength.
Chromatic dispersion characteristics of optical fibers with near zero magnitude and slope is very important for such applications as optical transmission systems, dispersion compensation, and nonlinear optics. Theoretically-designed dispersion characteristics require a tolerance

Furthermore, flattened chromatic dispersion from 1450 nm to 1590 nm is obtained. Keywords. Photonic Crystal Fiber Chromatic Dispersion IEEE Photonic Technology Letter High Birefringence Total Dispersion.
for standard fiber at zero dispersion wavelength is S=0.085 ps/km- nm 2 . For dispersion-shifted fiber with ? ZD =1.55 ?m , a typical value of S is S=0.05 ps/ km-nm 2 . The S parameters is relevant mostly for systems: • Working close to a zero first order Section5-Dispersion in Optical Fibers 228a.
The sensitivity of the dispersion shifted and dispersion flattened single mode fibres to similar variations in the structural parameters is too infe- rior Such systems will probably use as transmission media dis- persion shifted or dispersion flattened single mode fibers with low attenuation and
