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.
