  • Modular broadband bidirectional programmable switch system with stacked modular switch arrangement
    Patent number: 5481073
    Abstract: The basic element of a modular, bidirectional broadband programmable switch system is a switch module having a thin rectangular housing with a single first connector preferably in the center of an elongated rear face and n second connectors equally spaced along the elongated front face. Broadband switches within the module selectively connect the single first connector with any one of the second connectors to provide an n.times.1 or 1.times.n switch. Up to n of the switch modules can be stacked side-by-side with an additional module extending transversely with its n second connectors connected to the first connectors on the stacked modules to provide an n.sup.2 .times.1 or 1.times.n.sup.2 switch. The first connectors on the additional modules of two such stacks can be connected to provide an n.sup.2.times.n.sup.2 switch.
