Research ArticleOpen accessIn the keywordsCustomer-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 keywordsPerformance Analysis of Different Optical Switching ArchitecturesSalman Ali Al-QahtaniProblem statement: Optical Packet Switching (OPS) and transmission networks based on Wavelength Division Multiplexing (WDM) have been increasingly deployed in the Internet infrastructure over the last decade in order to meet the huge increasing demand for bandwidth. Several different technologies have been developed for optical packet switching such as space switches, broadcast-and-select, input buffered switches and output buffered switches. These … …Journal of Computer Science, Vol. 7, Issue 8 · 14 Jul 2011 · 6,330 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalytical Analysis of In-Band Crosstalk, Out-of-Band Crosstalk and GVD-Based Power Penalties in DWDM and TDM/DWDM-PONSIbrahim Mohamed, Mohammad Syuhaimi Ab-RahmanIn addition to the ever-increasing demand for broader bandwidth per user, which results from the continuous development of new bandwidth-hungry services and applications, the consequent upgrade from the currently deployed Time-Division Multiplexing Passive Optical Networks (TDM-PONs) to Next-Generation Optical Access Networks (NG-OANs) has become inevitable. Different architectures for creating a NG-OAN have been proposed in the literature. Among those architectures, … …Journal of Computer Science, Vol. 11, Issue 3 · 13 May 2015 · 7,317 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Jitter Impact on High Speed Transmissions of Wavelength-Division Multiplexing NetworksHazura Haroon, Hanim Abdul Razak, Sahbudin Shaari, P. Susthitha MenonIn this study, we conduct a thorough assessment of the effect of jitter occurrence in high speed 10 Gbps and 200 GHz Wavelength-Division Multiplexing (WDM) optical network. First, we present a simulation model to study the effect of jitter presence in the proposed network and then determine the maximum amount of jitter which the network can withstand. The model is … …American Journal of Applied Sciences, Vol. 11, Issue 12 · 13 Jan 2015 · 6,673 accessesView PDFCite
Research ArticleOpen accessIn the abstractLow-Loss Hand-Made Demultiplexer using Transparent Color Filter in WDM-POF Network for Short-Haul Communication SystemMohd Syuhaimi Ab. Rahman, L. S. Supian, Hadi Guna et al.Problem statement: Polymer optical fiber has advantages compared to other alternatives communication media such as copper, coax cable and glass fiber. POF has bigger bandwidth compared to wireless communication network and POF is also free from electromagnetic disruption. Since POF is suitable for communication system up to distance of 100 m with data speed of 400 Mbps using polymer step-index … …Journal of Computer Science, Vol. 8, Issue 4 · 30 Jan 2012 · 7,087 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance of Thin-Film as Wavelength Filter in Wdm-Pof NetworkMohd Syuhaimi Ab. Rahman, L. S. Supian, Hadi Guna et al.Problem statement: Huge capacity for data transmission and bandwidth are becoming a need nowadays. High cost of implementation using optical fibers prevents utilization of the technology as wide as possible. Approach: Wavelength Division Multiplexing (WDM) was a technique that offers the solution for providing better bandwidth. WDM technique allows several signals that have different wavelengths to be transmitted in a … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 9 Dec 2011 · 7,270 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Analysis on 16-Channels Wavelength Division Multiplexing in Free Space Optical Transmission under Tropical Regions EnvironmentSalasiah Hitam, Siti Norziela Suhaimi, Ahmad Shukri Mohd Noor et al.Problem statement: Wavelength-Division-Multiplexing (WDM) is a promising technique for meeting the growing demand for increased bandwidth and various types of services in the optical access network. For wide area or metropolitan networks, fibers are deployed to provide huge bandwidth. In access networks, the fiber-to-the-home will partially solve the last mile problem. However, some environmentally sensitive area such as housing areas, … …Journal of Computer Science, Vol. 8, Issue 1 · 2 Nov 2011 · 10,358 accessesView PDFCite
Research ArticleOpen accessIn the abstractMPLS over Segmented WDM Optical Packet Switching NetworksHakim Mellah, Fouad M. AbbouWavelength Division Multiplexing (WDM) is a promising solution for data transport in future all-optical wide area networks. Such networks consist of fibers joined by dynamically controllable cross-connects which provide purely optical transport between pairs of network access stations. Optical packet switching (OPS) is optical switching with the finest granularity. Incoming packets are switched all-optically without being converted to electrical signal. … …Journal of Computer Science, Vol. 2, Issue 5 · 31 May 2006 · 6,750 accessesView PDFCite
