Abstract
A reconfigurable node for a hybrid fiber cable network includes fiber slots housing a transmitter or receiver interfacing to a head end, coax slots housing an RF brick interfacing with subscribers and RF plug-in modules providing connectivity between the fiber and coax slots. The plug-in modules include connection points, for connection to a fiber or coax slot. A fiber impedance element, associated with the transmitter or receiver in that fiber slot, is connected to each fiber slot. Each fiber impedance element has a different impedance value. A coax impedance element, associated with the RF brick in that coax slot, is connected to each coax slot. Each coax impedance element has a different impedance value. An impedance sensing circuit detects a DC level associated with each connection point which corresponds with the impedance element in a respective fiber or coax slot to determine the location of transmitters, receivers or RF bricks.
