Abstract:
A system capable of simultaneous bidirectional transmission of network and distribution signals comprising:(a) a bidirectional transmission facility; (b) a first diplexer; and (c) a second diplexer; (d) wherein (i) the first diplexer receives network signals from a first-diplexer input system, comprising (A) a first transmission facility, comprising twisted-wire pair cable, connected to a source of network signals, (B) a second transmission facility, comprising coaxial cable, connected to the first diplexer, and (C) means, comprising an impedance converter, connected to the first transmission facility and the second transmission facility, for converting signals using the first transmission facility for transmission using the second transmission facility, and transmits the network signals, using the bidirectional transmission facility, to the second diplexer; and (ii) the second diplexer receives distribution signals and transmits the distribution signals, using the bidirectional transmission facility, to the first diplexer.
