Research ArticleOpen accessIn the keywordsAnalytical 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 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 abstractOptical Code-Division Multiple-Access and Wavelength Division Multiplexing: Hybrid Scheme ReviewHesham A. Bakarman, P. Susthitha Menon, Isaac A.M. Ashour, Sahbudin ShaariProblem statement: Hybrid Optical Code-Division Multiple-Access (OCDMA) and Wavelength-Division Multiplexing (WDM) have flourished as successful schemes for expanding the transmission capacity as well as enhancing the security for OCDMA. However, a comprehensive review related to this hybrid system are lacking currently. Approach: The purpose of this paper is to review the literature on OCDMA-WDM overlay systems, including our hybrid approach … …Journal of Computer Science, Vol. 8, Issue 10 · 29 Aug 2012 · 7,859 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordEVALUATION OF HIDDEN MARKOV MODEL BASED ADAPTIVE PROVISIONING OF OPTICAL BURST SWITCHING NETWORKS AMENABLE FOR UPGRADATION TO GREEN FLEXIGRID NETWORKSP. G.V. Ramesh, Prita NairCatering to the evolving bandwidth-on-demand applications requires flexible provisioning architectures that ensure fairness to both high end and low end users of internet. Dynamic classification of network paths into long and short, based on traffic dependent connection holding times and a wavelength allocation from different subsets for these categories is a necessity for implementing energy saving hybrid switching, loss recovery … …Journal of Computer Science, Vol. 10, Issue 5 · 16 Jan 2014 · 6,517 accessesView PDF Cite
