Research ArticleOpen accessIn the keywordsLONG-REACH OPTICAL ACCESS NETWORKS (LR-OANS): A PROMISING CANDIDATE FOR FUTURE OPTICAL ACCESSI.M.M. Mohamed, M.S. Ab-RahmanThe ever-increasing demand for broader bandwidth per user, which results from the continuous development of new bandwidth-hungry services and applications, creates the motivation to upgrade the currently deployed Time-Division Multiplexing Passive Optical Networks (TDM-PONs) to Next-Generation Optical Access Networks (NG-OANs). Beside the need for more bandwidth per user, a further extension in the range and an increase in the split … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 15 Aug 2014 · 6,704 accessesView PDF Cite

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 PDF Cite

Research ArticleOpen accessIn the abstractEnergy Consumption and Environmental Implications of Wired Access NetworksSlavisa Aleksic, Ana LovricProblem statement: Wired broadband Internet access can be realized using various technologies, configurations and protocols. It is widely deployed and able to provide both high data rates and high reliability. These features are of strong importance for many advanced applications. Since the number of broadband subscribers worldwide grows exponentially, the power efficiency of access networks becomes increasingly important. Approach: The … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 18 Jan 2012 · 8,763 accessesView PDF Cite

Research ArticleOpen accessIn the abstractLow-Cost Encoding Device for Optical Code Division Multiple Access SystemMohammad Syuhaimi Ab-Rahman, Boonchuan Ng, Norshilawati Mohamad Ibrahim, Sahbudin ShaariProblem statement: Instead of using Fiber Bragg Grating (FBG) to develop the coded spectrums, which consist of expensive elements, the grating also are highly sensitive to environmental changes and this will contribute to the increment of capital and operational expenditures (CAPEX and OPEX). Approach: This study presented the development of low-cost 16-ports encoding device for Optical Code Division Multiple Access … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,638 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordMetro Access Convergence for Broadband Future Low Energy Consumption NetworksG.M. Tosi Beleffi, E. Leitgeb, G. Incerti et al.Problem statement: In study the impact of the optical technologies and infrastructures on the reduction of the carbon footprint maintaining high level of broadband to the end user is discussed. Approach: Authors analyze the main energy consumers in Core, Metro and Access Networks as well as the topology and the performaces of the EU FP7 SARDANA Project, a long reach … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 12 Jan 2012 · 7,646 accessesView PDF Cite
