An electrical device includes signal ports, transformers, and a differential mode device. The transformers are in communication with the signal ports, respectively. The transformers are configured to receive input signals, respectively, from the signal ports. Each transformer is configured to inject the respective input signal onto a pair of output lines of the transformer. The differential mode device is connected to a first output line of the pair of output lines of a first transformer exclusive of connection to a second output line of the first transformer. The differential mode device is configured to inject a signal from the first output line onto the pair of output lines of a second transformer. Signals from the pair of output lines of the second transformer are injected onto a pair of conductors, respectively, of a communications medium.

Electrical device for multiple-signal injection onto multiple-conductor communications medium

A transmission medium includes inductive couplers, signal lines and conductors. Each of the signal lines is configured to receive a respective one of multiple input signals. Each of the signal lines extends through at least one of the inductive couplers and is configured to inductively transmit one of the input signals to the at least one of the inductive couplers. Each of the conductors is configured to extend through at least two of the inductive couplers. The conductors include a first conductor and a second conductor. The inductive couplers are configured to inductively transmit the input signals to the conductors to generate a first current and a second current. The first current flows in the first conductor and towards an output of the first conductor. The second current flows in the second conductor and towards an input of the second conductor.

Transmission medium with inductive current transmission on multiple conductors

The techniques described herein permit the application of methods for increasing the performance of a communications system on a medium made up of N conductors and a reference plane by means of injecting signals inductively in up to N combinations of the conductors, including injection in common mode, such that said injected signals can be made to be orthogonal to each other.
