Abstract

Systems and methods are described for long subscriber loops using modified load coils. A method includes providing a circuit to extend a transmission medium, the circuit including an inductor and a shunt network, the inductor including a first leg and a second leg, the shunt network including a first circuit portion and a second circuit portion, the first circuit portion including a first capacitor and a first resistor, the first capacitor disposed in a parallel relationship across the first leg of the inductor, the first resistor disposed in a parallel relationship across the first leg of the inductor, the second circuit portion including a second capacitor and a second resistor, the second capacitor disposed in a parallel relationship across the second leg of the inductor, the second resistor disposed in a parallel relationship across the second leg of the inductor; providing an inductive admittance from the first leg of the inductor to a first communication transmitted within a first frequency band; and providing a capacitive admittance from the first circuit portion of the shunt network to a second communication transmitted within a second frequency band. An apparatus includes a circuit including an inductor and a shunt network, the inductor having a first leg and a second leg, the shunt network including a first circuit portion and a second circuit portion, the first circuit portion including a first capacitor and a first resistor, the first capacitor disposed in a parallel relationship across the first leg of the inductor, the first resistor disposed in a parallel relationship across the first leg of the inductor, and the second circuit portion including a second capacitor and a second resistor, the second capacitor disposed in a parallel relationship across the second leg of the inductor, the second resistor disposed in a parallel relationship across the second leg of the inductor, the first leg of the inductor provides an inductive admittance to a first communication transmitted within a first frequency band, and the first circuit portion of the shunt network provides a capacitive admittance to a second communication transmitted within a second frequency band.
