ABSTRACT:
A hybrid fiber coax communications system includes plural coaxial distribution plants, fiber optic nodes, fiber optic links and a headend. At least one subscriber is coupled to each coaxial distribution plant. In the upstream signal path, the upstream signals travel from the coaxial distribution plants to the fiber optic nodes and through the fiber optic links to the headend. In the headend, optical receivers receive each upstream signal and pass the signals to respective node switches. The node switches selectively connect the upstream signals to a demodulator. An element control manager provides a control signal to the node switches to control whether the switch is in an open or closed state. One of the switches can be selected to be closed so that the demodulator receives one of the upstream signals.
