The chromatic dispersion of fiber is a major factor
causing distortion of the light signals, and if not being
addressed using accurate compensators it will lead to a
significant deterioration in the performance of optical system.
The value of chr
omatic dispersion is not fixed along the fiber,
and this necessitates the use of tunable dispersion
compensators which need information about the value of
dispersion which is done by dispersion monitoring.
This research is Interested in analyzing chromatic
dispersion technique based on the measuring of clock tone
power of transmitted data and which is commensurate with
the dispersion of the fiber. We found the relationship between
signal frequency with range and accuracy of measurement.
Also, the advantage of this technique to provide feedback
signal to tunable dispersion compensator. The results show
the extent of the improvement made in network performance.
VPItransmissionmaker program was used to simulate
the technique proposed.
This research aims to study and design a single mode optical fiber using simulation,
with a core and glass cladding, and also helps in ensuring the efficiency to use the optical
fiber designed within the broading window C-Band,and that these resear
ches and studies
tries to use this window. This research also shares to set the light on the Numerical
Programmes and Simulation used now in studying and designing these optical fibers. At
first we used the programOptifiberto reach the confidence of Sellmeier equation for the
fiber core, and this completed by using the finite element method solving the equation of
propagation the electric field and finding its 3-D distribution, using the famous simulating
COMSOLMultiphysics. This completed by putting the program MATLAB to reach the
two equation: the total dispersion and attenuation for the designed optical fiber.
