يهتم هذا البحث بتحليل أداء مكونات شبكات NG-PON2 و خصائص هذه الشبكات من خلال نموذج لنظام مكون من أربع أزواج من الأطوال الموجية لتخديم 8 مشتركين بمعدل نقل متماثل على كلا الوصلتين يساوي 40Gbps و يظهر النموذج المصمم باستخدام برنامج OptiSystem نتائج جيدة تعطي صورة واضحة عن سلوك مثل هذه الأنظمة.
This study examines the most important component of NG-PON2 networks and the characteristics of these network through a model of a system consisting of four pairs of wavelengths to serve 8 subscribers 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.

Wireless Broadband is the meeting point between two of the most important growth stories in telecommunications industry . The broadband technologies have achieved great success in recent years , which is the same thing that happened with wireless com
munication technologies
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 wav
elength .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 restoration of the network from failure got through different
mechanisms and algorithms at different levels of network in particular
time. Recovery methods of optical network based on GMPLS Do not take
any consideration for the integration of
communication when it establish
the backup path, which can lead to greater harm, such as the failure may
occur to a link or a path in which a large number of contacts concentrated.
Also, such concentration may leads to a negative impact in terms of the
network survivability.
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.
this research studies 2x2 MIMO LTE signal transmission from the
main tower eNB and the relay node RN over single mode fiber
using ROF technology and take advantage of the WDM technology,
the results show the ability of ROF to accommodate MIMO
com
munication with high efficiency.
The network has been simulated and analyzed using Optisystem
program, and the results were more than promising.
