Research ArticleOpen accessEvery word in the titleA Six-Port Reflectometer Calibration Using Wilkinson Power DividerTraii Moubarek, Ali GharsallahA new calibration method for a six-port reflectometer which minimizes the effect of power measurement errors is presented. It is based on the power divider correlator to obtain estimates of the six-port calibration constants. The calibration procedure is to determine the constants that govern the operation of the six-port from the measurement of power or output ports tensions by placing … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 17 Mar 2016 · 7,798 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOptical System Monitoring Based on Reflection Spectrum of Fiber Bragg GratingMohammad Syuhaimi Ab-Rahman, Nani Fadzlina Naim, Mastang Tanra, Harry RamzaProblem statement: This study presents fiber fault monitoring approaches for Fiber-to-the Home (FTTH) with a Passive Optical Network (PON). Current fiber fault monitoring approaches are difficult to be implemented due to its complexity and high loss as the amount of branches increase. Approach: A fiber fault monitoring scheme is proposed whereas Fiber Bragg Grating (FBG) is placed on each branch … …Journal of Computer Science, Vol. 8, Issue 6 · 28 Apr 2012 · 7,191 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUse of Optical Reflectometry to Observe Various Concentrations of GlucoseHariyadi SoetedjoProblem statement: Monitoring technique on glucose is a hot topic as this compound has been considered to be important in human healthties. Optical reflectometry has been used to study various concentrations of glucose dissolved in the water. Approach: The self-construction of reflectometer used was of hemi-cylinder aluminum to allow light beam strikes the sample at 70° for sor p-polarization state. … …American Journal of Applied Sciences, Vol. 8, Issue 5 · 17 May 2011 · 7,144 accessesView PDF Cite
