Abstract
A connector integrates a transformer and a “phantom” power provision, thus enabling a reduction in size along with an increase in versatility for electronic communication. The transformer may comprise a pair of magnetic transformers. The power source may be connected to center taps of the magnetic transformers for providing a bias voltage to the connector.
Claims42
A connector for receiving and transmitting electronic signals comprising:
- a connecting port-within a chassis, said connecting port having a plurality of input connections on a chip side of the connecting port and a plurality of output connections on a cable side of the connecting port, said plurality of input connections connecting to a first receiver port, a second receiver port, a first transmitter port and a second transmitter port;
- a transformer within said chassis connecting to said plurality of input connections and said plurality of output connections, said transformer having a winding with a tap on the cable side of the connecting port;
- and
- a power connection within said chassis connecting to said tap and to a fixed potential, said power connection being connectable to a remote power source.
