Abstract
A wideband signal distribution system for distributing among a plurality of outlets wideband signals modulated onto RF carrier signals within a specified frequency band. The system functions as "passive" infrastructure and includes a distribution unit having a plurality of input ports, a plurality of output ports, a transmission path, a combiner for applying signals appearing at the plurality of input ports to the transmission path, and a splitter for applying signals appearing on the transmission path to all of the plurality of output ports. The system further includes a plurality of cables selected from the class of fiber optic cables, coaxial cables, and twisted pair wire cables, each extending between a respective one of the distribution unit ports and a respective one of the plurality of outlets, and a plurality of impedance matching devices, where such devices are appropriate for the type or types of cable used. Each of the devices terminates a respective end of a respective one of the cables. Distribution units can be cascaded utilizing combinations of cable, such as coaxial cable or optical fiber cable, to enhance functionality of the system.
