Abstract
A system and method for transmitting Ethernet packets in full duplex mode over transmission medium such as a single coaxial cable or a twisted pair of wires by separating the signals by a receive amplifier that subtracts the transmit reference from the combined waveform contained on the coaxial cable.
Claims16
A communication system comprising a device:
- a first connector arranged for a first transmission format, wherein the first transmission format has a first number of transmission lines;
- a second connector arranged for a second transmission format, wherein the second transmission format has a second number of transmission lines wherein the second number of transmission lines is less than the first number of transmission lines;
- a first circuit operatively connected to both the first connector and the second connector that combines signals in the first transmission format at the first connector to the second transmission format at the second connector;
- and
- a second circuit operatively connected to both the first connector and the second connectors, the second circuit separating signals received in the second transmission format into the first transmission format, wherein the second circuit employs prior knowledge of at least one signal within the first transmission format to separate signals received at the second connector in the second transmission format into signals of the first transmission format at the first connector.
2 more elements
A method for transmitting Ethernet signals across transmission mediums comprising:
- transmitting Ethernet signals from a first end of a transmission medium to a second end of the transmission medium;
- detecting a series of Ethernet signals at the second end of the transmission medium;
- and removing a portion of the series of Ethernet signals detected at the second end of the transmission medium that are being transmitted from that second end towards the first end to acquire a received signal at the second end.
