Abstract

A CATV/MoCA signal distribution system includes a first 2-way hybrid splitter for receiving a CATV input signal and splitting it into first and second CATV output signals, a second 2-way hybrid splitter for receiving the second CATV output signal and splitting it into third and fourth CATV output signals, with the latter being connected to a CATV output port. A first diplex filter is receptive of the first CATV output signal, and MoCA signals for providing electrical isolation therebetween and connecting them to a modem port. A second diplex filter is receptive of the third CATV output signal and MoCA signals for providing electrical isolation therebetween and connecting them to a Gateway port. A resistive splitter is connected between the first and second diplex filters and a plurality of individual MoCA signal ports for providing bidirectional MoCA signal flow therebetween.
