Journal ArticleDOI
Performance Analysis of a Free Space Optics Link with Multiple Transmitters/Receivers
TL;DR: In this article, the received power level (PR) and bit error rate (BER) are considered to influence the Free Space Optics (FSO) link performance and the relationship between the two parameters are investigated and analyzed.
Journal ArticleDOI
An overview of laser principle, laser–tissue interaction mechanisms and laser safety precautions for medical laser users
Mohammed M. Jawad,Abdul Qader Sarah T.,A. A. Zaidan,B. B. Zaidan,Ahmed Wathik Naji,Abdul Qader Ibraheem T. +5 more
TL;DR: It is important for the medical laser users to have a fundamental understanding of qualitative laser technology and essential operation of those lasers with biological tissues to avoid serious damage on the tissue of both patient and laser operation personnel.
Proceedings ArticleDOI
The effect of weather on free space optics communication (FSO) under tropical weather conditions and a proposed setup for measurement
TL;DR: The objective of this paper is to produce analysis result of the different weather attenuations that have effect on FSO link and to provide more knowledge on the feasibility of FSO deployment under tropical weather condition especially for a long range link.
Journal ArticleDOI

Ahmed Wathik Naji,Belal Ahmed Hamida,X.S. Cheng,Mohd Adzir Mahdi,Sulaiman Wadi Harun,Sheroz Khan,Wajdi Fawzi Mohammed Al-Khateeb,A. A. Zaidan,B. B. Zaidan,Harith Ahmad +9 more
TL;DR: In this article, the authors present an overview of most of the Erbium-doped fiber amplifier (EDFA) configurations that have been proposed in order to provide the researchers with a clear view of what has been done in this field.
Journal ArticleDOI
Analysis of Rain Effects on Terrestrial Free Space Optics based on Data Measured in Tropical Climate
TL;DR: In this article, the authors compared rain attenuation predicted by models and data measured in Malaysia over Free Space Optical links for one year period, and concluded that prediction models are clearly unable to predict attenuation measured in tropical climate.
