  • High-Speed Copper and Coaxial Broadband
    IEEE Communications Magazine, 2019
    Co-Authors: Jochen Maes, Rainer Strobel, Anas Al Rawi, Mahdia Ben-ghorbel
    Abstract:

    The articles in this special section addresses copper technologies and deployment practices beyond those currently available. Legacy copper infrastructure originally designed to provide voice services (twisted pair Network) or television services (Coaxial Network) has performed vastly beyond specification and continues to deliver increased broadband speeds. Today’s mature technologies like vectored VDSL2 and G.fast for twisted pair and DOCSIS 3.1 for Coaxial Networks, are able to surpass present-day demand for broadband speeds in excess of several hundreds Mb/s per end user. The ability to off er gigabit speeds has been fueled by advances in digital signal processing and by a steady migration toward fiber rich access Networks where only the last “mile” into the homes remains copper based (FTTx). We often get the question why the industry continues to consider copper access, while fiber is perceived as superior in terms of transmission properties.

  • Hybrid Fiber Coaxial Network Design
    Operations Research, 2002
    Co-Authors: Raymond A. Patterson, Erik Rolland
    Abstract:

    Much interest exists in broadband Network services to deliver a variety of products to consumers, such as Internet access, telephony, interactive TV, and video on demand. Due to its cost efficiency, Hybrid Fiber Coaxial (HFC) technology is currently being considered by most Telcos and cable companies as the technology to deliver these products. The topological HFC Network design problem as implemented by several major companies is a form of the capacitated tree-star Network design problem. We propose a new formulation for this problem and present a heuristic based on hierarchical decomposition of the problem. The proposed solution methodology exploits an Adaptive Reasoning Technique (ART), embedded as a meta-heuristic over specialized heuristics for the subproblems. In this context, we demonstrate the dynamic use of an exact solution technique within ART. The generalizability of the proposed solution methodology is demonstrated by applying it to a second problem, the Traveling Salesman Problem (TSP). Computational results are presented for both the HFC Network design problem and the TSP, indicating high-quality solutions expending a very modest computational effort. The proposed solution method is found to be effective, and is shown to be easily adaptable to new problems without much crafting, and as such, has a broad appeal to the general operations research community.

  • Modelling subsea Coaxial cable as FIR filter on MATLAB
    AIP Conference Proceedings, 2011
    Co-Authors: D. Kanisin, M. S. Nordin, M. H. Hazrul, E. A. Kumar
    Abstract:

    The paper presents the modeling of subsea Coaxial cable as a FIR filter on MATLAB. The subsea Coaxial cables are commonly used in telecommunication industry and, oil and gas industry. Furthermore, this cable is unlike a filter circuit, which is a “lumped Network” as individual components appear as discrete items. Therefore, a subsea Coaxial Network can be represented as a digital filter. In overall, the study has been conducted using MATLAB to model the subsea Coaxial channel model base on primary and secondary parameters of subsea Coaxial cable.
