إن قراءة تاريخية مختصرة تظهر أن كمية المعلومات المتبادلة في شبكات الاتصالات تواصل ازديادها بصورة مدهشة نتيجة تطوير خدمات اتصال جديدة، و لكن مع زيادة معدل نقل البيانات يعاني النظام الضوئي من تدهور الأداء بسبب التشتت، الذي تم أخذه بالحسبان في هذا البحث. حيث إن تخفيض الضياعات الناتجة عن التشتت مسألة هامة في الشبكات الضوئية، و تعتبر شبكة براغ الليفية Fiber Bragg Grating(FBG) من أهم مكونات نظم الاتصالات الضوئية، و إحدى الطرق الفعالة المستخدمة لتحقيق هذه الغاية. تمت في هذه المقالة دراسة تأثير استخدام FBG كمعوض للتشتت في نظم الاتصالات الضوئية، حيث قمنا بمحاكاة نظام اتصالات ضوئي يستخدم FBG، و درسنا تأثير بارامترات كل من مضخم الليف المشاب بالإيربيوم Erbium Doped Fiber Amplifier(EDFA) و شبكة براغ و الليف الضوئي المستخدم على أداء هذا النظام، و تم إيجاد أفضل القيم لبارامترات هذا النظام. اعتمد نموذج المحاكاة المدروس على برنامجي Optisystem7 و Matlab. و تم تقييم النتائج بالاعتماد على المخطط العيني الناتج عن المحاكاة و المعاملين Q و معدل خطأ البت (BER)Bit Error Rate.
Studying is showed that the amount of exchanging information in the network surprisingly grows due to developing new communication services. But, when data rates increase the optical system performance degrades due to dispersion, which was taken into account in this research. Where as the reduction of dispersion losses is important in optical networks. Fiber Bragg Grating (FBG) is one of the most important components of optical communication systems, and one of the effective methods used for this goal. This article tests the effect of using FBG as dispersion compensator in optical communication systems, where we simulate optical communication system using FBG. And study the effect of Erbium Doped Fiber Amplifier (EDFA) and FBG and fiber optic parameters on this system performance, and it has been finding the best values of the system parameters. Which the simulation model depended on two Optisystem7 and Matlab software. We evaluate performance through eye diagram and two factors Q, Bit Error Rate (BER).

Optical fiber is one of the most important communications media in communication
system. Due to its versatile advantages and negligible transmission loss it is used in high
speed data transmission. There are various types of optical fiber, the Fibe
r Bragg Grating
(FBG) is commonly chosen as important components to compensate the dispersion in
optical communication system. Because the low cost of filter for wavelength selection and
low insertion loss, it has also customized reflection spectrum and wide bandwidth. The
simulation of transmission system will be analyzed based on different parameters using
OptiSystem simulator. By simulating a model of communication system and using the
most suitable settings of the system which include input power, fiber cable length (km) and
attenuation coefficient (dB/km) at cable section, there are three different parameters will be
investigated, which are Signal power, Noise power, output power at receiver.
We determined the optimal length of the fiber amplifier theoretically by solving
numerically set of differential equations of a single stage and one pass amplifier, using
MATLAB. Input values, as doped density, core radius, pumping power and input signal
were changed, and the optimal fiber length was calculated.
This paper is concerned with an original analysis of an multiple pulse
position modulation (MPPM) scheme using graded-index plastic optical
fiber.
The aim of this research is to study of detection sensitivity in optical preamplifier, which is used
as a first stage in optical receivers. This subject is important because it is used in laser
rangefinders. The parameters that affect the distance
measurement using time of flight
technique are studied in details. Then, noise analysis and signal to noise ratio calculation are
performed in preamplifiers to detect a signal with pulse width of 30ns using Matlab. The study
results are applied to some preamplifiers to determine the minimum detectable power.
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.
