يقترح البحث إجراء تطوير في بنية وحدة الشبكة الضوئية عبر إدخال مرشح ضوئي صرف قادر على التعامل مع تقنية التجميع بتقسيم طول الموجة ( WDM: Wavelength Division Multiplexing ) و تقنية التجميع بتقسيم الاستقطاب (PDM: Polarization Division Multiplexing ) بنفس الوقت مما يمكننا من إرسال قناة على المركبة الأفقية للشعاع الضوئي وأخرى على المركبة الشاقولية على نفس طول الموجة. تسمح تقنية التجميع الهجين WDM-PDMبإيصال ضعف عدد القنوات إلى المشترك دون أي تغيير في البنية التحتية بين المقسم الضوئي و المشترك. يبرهن البحث أولا صحة فكرة استخدام التجميع الهجين WDM-PDMُ باستخدام برنامج معروف في مجال الشبكات الضوئية OptiSystem7.0 ثم يدرس البحث فعالية استخدام المرشح الضوئي المقترح إدخاله في بنية ال ONU من أجل ثلاث حالات للشبكات الضوئية : WDM-PDM للوصلة الهابطة، WDM(Downstream)/( TDM(Upstream )، WDM(Upstream)/WDM(Downstream) بحسب توصيات اتحاد الاتصالات الدولي.
This research proposes the development of Optical Network Units by introducing an all optical Filter. This optical filter can treat WDM and PDM technology at the same time enabling us to send a channel on the horizontal and vertical of the same wavelength .The hybrid WDM-PDM technology allows to delivery double channels for users without any changing in infrastructure between optical central office and user . Firstly , this article prove the idea of hybrid WDM-PDM technology by OptiSystem7.0 simulator, secondly we study proposed all optical Filter for three cases of optical access: WDMPDM( Downstream), WDM(Downstream)/( TDM(Upstream) , WDM(Downstream)/ WDM(Downstream) recommended by the international communication federation, ICF.

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.

with symmetrical transmission on both tow links equal to 40Gbps, The
proposed model designed using OptiSystem program shows good
results that give a clear view of the behavior of such systems.

This paper presents an analytical study on improving the performance of virtual

Optical filter is one of the most accurate and important elements in pure optical communication network which uses wavelength division multiplexing (WDM). This research includes studying Acousto Optic Tunable Filter (AOTF) in linear anisotropic mediu
m, which depends on the interaction principle between optical waves and acoustic waves.
This paper describes simulating and testing the AOTF in MATLAB/Simulink software which is a strong tool for simulating and designing various systems. We have achieved an AOTF model, and created special block which could be added to MATLAB Simulink Library. We have also evaluated the performance of this filter and its ability to select one wavelength between the set combined by WDM. Moreover, we have studied the effect of acoustic wave frequency, its velocity, the properties of the crystal used in manufacturing it, and other influent parameters, along the selected wavelength.
