Abstract:
1. A differential bidirectional coupler coupled to the communication path of a first and second network device, the first and second network devices communicating by use of a differential full-duplex bidirectional data stream comprising a first differential data component and a second differential data component, the first differential data component transmitted from the first network device and the second differential data component transmitted from the second network device, the differential bidirectional coupler comprising: a first differential node operably connected to the first network device; a second differential node operably connected to the second network device; wherein the first differential node is configured to at least partially pass the first differential data component from the first network device to the second network device and the second differential node is configured to at least partially pass the second differential data component from the second network device to the first network device; a third coupler node configured to directionally couple a third data component comprising at least a portion of the first differential data component; and a fourth coupler node configured to directionally couple a fourth data component comprising at least a portion of the second differential data component.
