تعد تقنية الألياف الضوئية من أهم تقنيات الاتصالات السلكية لما تتمتع به من مزايا كثيرة، أهمها: سعة قناة كبيرة. تخامد صغير جداً. ممانعة للتداخل. السرية و صعوبة التنصت. أدت هذه المزايا لزيادة استخدام الوسائط الضوئية في التطبيقات المدنية و العسكرية على حد سواء, و على الرغم من كونها ذات سريّة عالية، فإنّ الألياف الضوئية مثلها مثل أي وسط ناقل للمعلومات تتعرض ، باستخدام أساليب متطورة ، للكثير من الاختراقات و السرقات و التجسس. نناقش في هذا البحث أمن نقل المعلومات عبر الألياف الضوئية الذي يعتبر من المواضيع الهامة في نظم الاتصالات الضوئية ، و سنقوم باقتراح بنية لكشف الاختراق عند حدوثه، و ذلك بالاعتماد على أنماط الانتشار و الاستطاعات الضوئية, إضافةً لتقديم خوارزمية تحدّد مكان الاختراق، و تبين النتائج بمحاكاة تنسجم مع الواقع العملي، لتساهم بشكل تطبيقي في ضمان سرية نقل المعلومات عبر شبكة الألياف الضوئية المعتمدة.
Fibre optics have greatly developed over the past decades, making it usable in wired communication systems. It has many advantages such as: High channel capacity. Interference immunity. Low loss. Security & Immune to intrusion. That’s why it became so popular in different types of usage. This article discusses the security of fibre optics, proposes an intrusion detection system able to detect different intrusion techniques, and specifies the intrusion point depending on modes and optical powers.

With the recent advances in the field of network security, a technique called
Intrusion Detection System IDS is developed to further enhance and make network secure.
It is a way by which we can protect our internal network from outside attack, and
can take
appropriate action if needed. Using intrusion detection methods, information can be
collected from known types of attack and can be used to detect if someone is trying to
attack the network. Many techniques are there to detect intrusion in a network like
signature matching, anomaly based and others.
The work presented here studies and compares the techniques used by intrusion
detection systems, and focuses on the signature matching technique. It discusses the open
source, free intrusion detection system Snort. Another open source intrusion detection
system Bro is also discussed. It compares these systems alarms against the open source
tool IDSWakeup.
The aim of this paper is to determine the best optical-probe
geometry that would help to detect neoplastic lesions in oral
epithelial tissue. Two Geometrical configurations are investigated.
The first one implements different distances between the
illumination and collection fibers, and the second one implements
different fiber diameters.
Both of these geometries are evaluated for their collection efficiency
and depth resolution. The effect of numerical aperture (NA) and
tissue optical properties on the fluorescence signal are also studied.
Optical properties of dysplastic tongue epithelial multi-layered
tissue were used as an input for Monte Carlo simulation. The results
show that the sensitivity to superficial layers can be achieved using
small fiber diameters. On the contrary, the sensitivity to deeper
layers can be achieved using larger distances between illumination
and collection fibers.
Recent works show that the graph structure of sentences, generated from dependency parsers, has potential for improving event detection. However, they often only leverage the edges (dependencies) between words, and discard the dependency labels (e.g.
, nominal-subject), treating the underlying graph edges as homogeneous. In this work, we propose a novel framework for incorporating both dependencies and their labels using a recently proposed technique called Graph Transformer Network (GTN). We integrate GTN to leverage dependency relations on two existing homogeneous-graph-based models and demonstrate an improvement in the F1 score on the ACE dataset.
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.
