  • Methods and apparatus for transferring digital packet-based data
    Patent number: 7841871
    Abstract: In accordance with a disclosed example method, a first coaxial port is connected to a connector casing. The first coaxial port is connectable to a first section of coaxial cable and the first port to receive digital packet-based data from a first device. A second coaxial port is connected to the connector casing. The second coaxial port is connectable to a second section of coaxial cable. A first impedance is electrically connected to the first coaxial port. The first impedance located in the connector casing. A second impedance is electrically connected to the second coaxial port. The second impedance is located in the connector casing and is different from the first impedance to create an impedance imbalance between the second port and the second section of the coaxial cable.

  • Method and apparatus for transferring digital packet-based data
    Patent number: 7635270
    Abstract: An impedance imbalance connector is provided. The connector comprises a first port connectable to a first section of coaxial cable, the first port having a first impedance and the first port further to receive digital packet-based data from a first device. The connector further comprises a second port connectable to a second section of coaxial cable, the second port having a second impedance which differs from the first impedance so as operationally to create an impedance imbalance between the second port and the second section of the coaxial cable.
