Research ArticleOpen accessPhrase in the titleNew Optical Splitter Design for Application in Fibre-to-the Home Passive Optical Network using Virtual Lab PlatformMohd Syuhaimi Ab-Rahman, Ainon Najahah Abdul Aziz, Aimi Amalin Khairuddin et al.Problem statement: In this study, authors present a new design of optical splitter to be applied in FTTH-PON named Multi Ratio Optical Splitter (MROS). MROS was introduced to enhance the power distribution in the optical network. Approach: We also bring in new approach for designing a new optical device that enable us to characterize and analyze the design from waveguide … …Journal of Computer Science, Vol. 8, Issue 6 · 16 Mar 2012 · 7,053 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleCost-Effective Fabrication of Self-Made 1×12 Polymer Optical Fiber-Based Optical Splitters for Automotive ApplicationMohammad Syuhaimi Ab-Rahman, Hadi Guna, Mohd Hazwan Harun et al.Problem statement: Multimode fiber cables can conduct many light rays and can operate free of disruption and with a greater bandwidth than a wireless connection. However, due to a slight variation in the speed of the light rays through the multimode fiber, a signal transmitted by all of these rays becomes spread out. Consequently, the signals become broader and therefore … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,925 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCustomer-Made 3×3 Polymer Optical Fiber Splitter Based on Green Technology using Fusion TechniqueMohammad Syuhaimi Ab-Rahman, Nik Nur Syahirah Mohammad, Hadi Guna et al.Problem statement: Polymer Optical Fiber (POF) has many advantages making it the choice of today’s communication, especially in automotive industry. This communication requires low cost ways for much information to be sent simultaneously. Because of this, using Wavelength Division Multiplexing (WDM) concept, a low cost and green 3×3 POF splitter is fabricated. It is fabricated using cheap and easy-to-find tools … …Journal of Computer Science, Vol. 8, Issue 4 · 11 Feb 2012 · 6,842 accessesView PDFCite
Research ArticleOpen accessIn the keywordsExamination of Plastic Filter on 1×N Fused-Taper-Twisted Polymer Optical Fiber DemultiplexerMohammad Syuhaimi Ab-Rahman, Latifah Sarah SupianProblem statement: In this study we propose the examination of the plastic filter on 1×3 POF demultiplexer. Approach: Three wavelengths are injected to the device which then split into three branches. Each branch is filtered by using specific color according to the pass through wavelength. Results: The developed demultiplexer is tested by transmitting signals through the polymer fiber-optic (10 meters … …Journal of Computer Science, Vol. 8, Issue 9 · 10 Aug 2012 · 7,119 accessesView PDFCite
Research ArticleOpen accessIn the abstractPower Analysis on Same Filter Different Sources for Selection of Spectral Filters in Optical DemultiplexerMohammad Syuhaimi Ab-Rahman, Hadiguna, Latifah Sarah SupianThe cost effective demultiplexer based on POF is reported in this study. The demultiplexer is fabricated by combining optical splitter with the suitable filter for wavelength selection. Therefore this study we aims to evaluate the effectiveness of selected color filter film for demultiplexer construction where only signals with certain wavelengths are allowed to pass through the demultiplexer while the other … …Journal of Computer Science, Vol. 9, Issue 7 · 18 Jun 2013 · 6,548 accessesView PDFCite
Research ArticleOpen accessIn the abstractRisk Reduction in Operations, Maintenance and Application for Customer Access NetworkMohammad Syuhaimi Ab-Rahman, Siti Asma Che Aziz, Kasmiran Jumari, Nurain Izzati ShuhaimiProblem statement: This study highlight on restoration scheme proposed against failure in working line at the drop region for Fiber-To-The Home (FTTH) with a Passive Optical Network (PON). Whereas PON is a system that brings optical fiber cable and signals all or most of the way to the end user. In this study we highlighted the issue on survivability scheme … …Journal of Computer Science, Vol. 8, Issue 3 · 17 Jan 2012 · 6,928 accessesView PDFCite
Research ArticleOpen accessIn the abstractProtection for an Immediate Split Structure of Tree-Based EPON Architecture-Ideal Condition AnalysisMohammad Syuhaimi Ab-Rahman, Siti Asma Che Aziz, Kasmiran JumariProblem statement: Ethernet Passive Optical Network (EPON) was proposed to overcome the bandwidth bottleneck at the Access Networks due to its simplicity, cost effective and wide spread deployment. A failure in access networks can cause serious problems, because access network transmit aggregated high speed traffic from hundreds of subscribers. Protection and restoration mechanisms have been applied in backbone networks, but … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 8,276 accessesView PDFCite
Research ArticleOpen accessIn the abstractQuantum Hadamard Gate Implementation Using Planar Lightwave Circuit and Photonic Crystal StructuresShamsolah Salemian, Shahram MohammadnejadAn all optical method has been proposed for quantum Hadamard gate implementation. This quantum gate was realized by using Y-junction beam splitter. Normal modes in waveguides have been used as quantum bit. This all optical gate can be used in quantum computation and communication. The proposed Hadamard gate has potential of being more compact and easily realized compared to other … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 7,921 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordCoherent Polarization Shift Keying Modulated Free Space Optical Links Over a Gamma-Gamma Turbulence ChannelX. Tang, Z. Ghassemlooy, S. Rajbhandari et al.Problem statement: The optical signal propagating through the Free Space Optical (FSO) channel suffers from irradiance and phase fluctuations caused by the atmospheric turbulence, which results in Bit Error Rate (BER) performance degradation. Approach: In this study the performance of the Multilevel Coherent Polarization Shift Keying (M-POLSK) based FSO communication system operating over the gamma-gamma turbulence channel is investigated.
