Design of low dispersion flattened optical fiber

الملخص EN

Dispersion of the transmitted optical signal causes distortion for both digital and analog transmission along optical fibers.

When considering the major implementation of optical fiber transmission which involves some form of digital modulation, then dispersion mechanisms within the fiber cause broadening of the transmitted light pulses as they travel along the channel.

This paper demonstrates that non-zero dispersion flatting optical fiber is achievable with dispersion extended over more than spectral range of 300nm.

A total dispersion of (0.0398444 ps / nm.

km) is obtained due to a design of an optical fiber with triple-clad at wavelength of 1551nm.

Also the flatting optical fiber is tested using computer simulation at two distances at 50km and 100km.
