  • NXN switch fabric partitioning
    Publication number: 20030174698
    Abstract: A switch fabric architecture for a telecommunications system is described. In a basic aspect of the invention a N×N switch fabric and associated line cards are combined into a single shelf. In a 2N×2N switch fabric architecture, two shelves, each having a 2N×2N switch fabric with associated line cards, and 2:1 and 1:2 selectors are interconnected with inter-shelf cabling and in a 4N×4N switch fabric architecture, four such shelves are interconnected with appropriate inter-shelf cabling.

  • Data path architecture for light layer 1 OEO switch
    Publication number: 20020122223
    Abstract: The light layer 1 OEO data path system architecture of the present invention provides a solution to the data opaqueness (i.e. protocol and data rate specific) of traditional OEO optical cross-connect switches (e.g. SONET/SDH OXC) and the full optical transparency issues of all optical photonic switches. More specifically, the documented light layer 1 OEO data path system architecture of the invention solves numerous identified problems for SONET/ISDH OEO cross-connect and all optical photonic switches.
