يهدف البحث إلى دراسة إمكانيات الحصول على مواد ذات تبدد مادي مزاح نحو الأطوال الموجية الأعلى و التي تقع ضمن النافذة C-Band المستخدمة حالياً في أنظمة الاتصالات بالألياف البصرية. يتم ذلك عن طريق إشابة مادة السيليكا النقية SiO2 بمواد مختلفة و بنسب مختلفة، حيث نقوم بإيجاد قرائن انكسار مادة اللب في ليف بصري و دراسة تغير هذه القرائن بتابعية الطول الموجي للضوء انطلاقاً من ثوابت سيلمر التي تم الحصول عليها من برنامج OptiFiber. بعد ذلك قمنا بحساب معامل التبدد المادي DM لكل من المواد المدروسة، بكتابة برنامج ماتلاب خاص بهذه الدراسة و بالتالي دراسة تغير التبدد المادي لهذه المواد بتابعية طول الموجة.
The aim of this study is to study the possibilities of obtaining materials with a material
shift to the higher wavelengths that fall within the C-Band window currently used in fiber
optic communication systems. This is done by mixing pure SiO2 with different materials
and different percentages. We find the evidence of refraction of the core material in an
optical fiber and study the change of these clues by sequential wavelength of light from the
solimer constants obtained from the OptiFiber program. We then calculated the physical
dispersion factor DM for each of the studied materials by writing a special matlab program
for this study and thus studying the change in the physical dispersion of these materials by
the sequential wave length.

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.
