إن الألياف البصرية هي واحدة من أهم وسائل الاتصال المستخدمة في أنظمة الاتصالات و قد تم استخدامها لنقل البيانات بسرعة عالية لمزاياها العديدة و الضياعات المهملة في عملية النقل، و يعتبر التشتت العامل الرئيسي الذي يحد من كفاءة الأداء. هناك أنواع مختلفة من معوضات التشتت في الألياف البصرية و لكن يعتبر ليف شبكة براغ FBG هو الأكثر استخداماً في تعويض التشتت في أنظمة الاتصالات البصرية، بسبب الكلفة المنخفضة للمرشح المستخدم لاختيار طول الموجة و انخفاض فقد الحقن، حيث يملك طيف انعكاس منفصل و عرض حزمة واسع. سوف يتم تحليل محاكاة لنظام الاتصالات استنادًا إلى معايير مختلفة باستخدام simulator Optisystem ، و اعتماد الإعدادات الأنسب للنظام و التي تشمل استطاعة الدخل و طول الكبل البصري (كم) و معامل التخامد (ديسيبل/كم) الخاص بالليف البصري، و حسبت ثلاث معلمات مختلفة و تشمل كلا من استطاعة الإشارة، استطاعة الضجيج، الاستطاعة الخارجة عند المستقبل.
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 Fiber 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.

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 in
to
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).
This research involves a simulation of four channels coarse wavelength division multiplexing (CWDM) transceiver. The study is done on the effect of the extinction ratio(ER) of the directly modulated laser (DML) diode, the effect of using Erbium doped
fiber amplifier (EDFA) in optical fiber links on the quality factor (Q) and the bit error ratio (BER) when using different lengths of fiber. Then a comparison is made between the CWDM network using the amplifier EDFA and the same network without using the amplifier EDFA. In addition, the study is done on the effect of optical fiber length on Q with and without the amplifier EDFA, and we demonstrated the relationship between them diagrammatically.
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.
Rice fading channel simulator is designed by
using two methods, method of Equal Areas (MEA) and method of
Exact Doppler Spread (MEDS). A new procedure for computation
of the parameters of the deterministic simulation model is
presented. This meth
od is named as combination of MEA and
MEDS.
Comparisons between autocorrelation functions of both reference
and simulation models are introduced for different procedures. It is
demonstrated by several simulation results that statistical properties
of simulation and reference models will be more closer according
to the new method than MEDS and MEA.
This research includes a simulation of optical code division multiple access system
transceiver (OCDMA) of the spectral amplitude coding (SAC). The study investigates the
effect of the pulse generator type used in the transmitter SAC-OCDMA of direc
t detection
technique and the effect of the length of the optical fiber on the signal quality factor (Q)
and on the bit error ratio( BER) . In addition a comparison is made between the SACOCDMA
system of direct detection technique and another one of complementary
subtraction technique in terms of signal quality factor and the bit error ratio when using
the same parameters for both systems.
