Abstract:
1. A method for communicating over a coaxial cable network, the method comprising: identifying at least one port in the coaxial cable network that provides high mutual isolation among nodes of the coaxial cable network when the port is terminated with an impedance that matches a characteristic impedance of coaxial cable in the coaxial cable network; terminating the identified port with an impedance that is substantially mismatched with the characteristic impedance of the coaxial cable; and transmitting a signal from a first node in the network to a second node in the network; wherein transmitting the signal from the first node to the second node comprises coupling a signal to the second node with an input impedance that is substantially mismatched with the characteristic impedance of the coaxial cable; and wherein the input impedance is larger than about 300% of the characteristic impedance of the coaxial cable.
