    • Present – Communication explosion

    • Future – Transport Revolution – Energy Revolution

    Chapter 1 Introductory Back Ground

    What is Communication Network

    Undersea Optical Fiber Networks

    Country A

    Country B

    Domestic Transport Network (OF,

    International Transport Network



    Local Area Node

    Both Domestic and International Transport will be on Optical Fibers. And Switching Nodes will be on NGN.

    Basic Components of Communication Networks

    • Following 8 major components can be identified – Geographical Location & Terminal – Access Networks – Local Exchange – Domestic Transport Network – International Exchange – International Transport Network – Other Country International Exchange – Other Country Domestic Network (With the similar

    components as above)

    Communication Network Paradigm Shift

    • Present – Transport Network

    • OF – Access Network

    • Shift from Copper to Radio (3G, EvDO) & Fiber • Immediate Future

    – Shift from Radio/OF to Power Line Communication System (PLC) depends upon which revolution comes first in future i.e. Transport or Energy (If energy comes first, access will not be PLC, but radio & OF)

    – Hence most promising access network for next 10y will be either Radio or OF or PLC. Cu network will gradually phase out.

    – Most promising transport network will be OF especially undersea OF cable systems

    Development of Access Network • Access Network is developed to accommodate integrated services

    such as Internet, IPTV, Data with Voice

    • Radio Options: 3G, EvDO, WiMAX • xDSL, PON, and PLC

    Convergence of Telecommunication

    Technological/Service Paradigm Shift All the technological development on Access and Transport will lead to customers to shift from traditional voice services to IP based data services without their knowledge

    Major Paradigm Shift

    • Increased Customer Expectations, Demand Growth

    • Lowest Cost, Huge Bandwidth and Durability • Technological Advancement (More Lambdas per

    Fiber - DWDM, 10G/lambda, Repeater Less Systems)

    • Improved Quality of Service Diversification

    Notes: Capacity figures denote lit, protected capacity at the end of the respective year. Capacity for 2004 is projected based on capacity upgrade announcements and new cable construction information as of March 2004. Capacity for 2005 and 2006 is projected assuming cables with upgradeable capacity will increase total capacity 20 percent each year until fully upgradeable capacity is achieved. Intra-Asia capacity includes cables with landings in both Hong Kong and Japan. Trans-Pacific capacity excludes Southern Cross and PacRim East. Trans-Atlantic capacity excludes Atlantis-2. Cables retired prior to year-end 2004 are excluded from Fully Upgraded capacity. Fully upgraded capacity is based on system design capacity.

    Matching the Demand with Available Facilities

    • Inter-continental traffic appears to be comparatively lower than the already installed designed capacity

    • Certain segments are saturated with designed capacity. – E.g. Traffic via Middle-East from Asia to

    Europe – This indicates the market trend in Asia and

    Middle East is much faster than Africa

    Most Promising Future Transport Media and where it applies

    • Transport: Optical Fiber (Especially for International transport Undersea cable)

    • Huge development in Asia and Asia towards
